Mcnearney, Eugene Master's Thesis
Analysis of Droplet-target interactions in electrostatically charged spraying systems A thesis submitted in partial fulfilment of the requirements for the degree of Master of Engineering, in Electrical and Electronic Engineering at the university of Canterbury by E. J. McNearney, B.E. Hons University of Canterbury, Christchurch, New Zealand December 2020. Abstract Increasing demands for food production and other agricultural products push demands for improved crop yields. Chemical pest management in the form of pesticides is a widely used method of increasing crop yields, over 90% of which is applied as liquid sprays. Poor application efficacy of these pesticides onto the target plant introduce concerns for both the environment and human health for those that come into contact. Traditional spraying techniques result in up to 70% off target losses, with less than 1% of the active chemical reaching the target pest. These losses are highly configuration dependent needing to be selected for the target plant and environmental conditions. One method to improve spray efficacy, electrostatically charging the liquid spray, has been previously introduced to market. This thesis has investigated factors influencing the liquid spray deposition onto the target, looking into plant impedances and using computer vision to quantify depositions with the ESS electrostatic nozzle. A high voltage power supply has also been developed to allow control of nozzle voltage. Leaf to ground impedances of potted grapevines were investigated as well as potential sources for the found values. It was found that the frequency and impedance relationship appears to follow dispersions found in other living tissues. It was also found that physical junctions in the plant where plant fibres intersect provided the largest impedance contributions with apparent linear regions in between. -

Thus, the converter with a voltage-doubler rectifier (VDR) has been snubber network is required across the output rectifier, which proposed. By combining the common part between a flyback results in a degraded efficiency. converter and a boost converter as a parallel-input/series-output As an attractive solution over aforementioned topologies, (PISO) configuration, this proposed circuit can increase a step- up ratio and clamp the surge voltage of switches. The secondary the flyback-boost (FB) converter was proposed as shown in VDR provides a further extended step-up ratio as well as its Fig. 1 [5], [6]. It can achieve a higher step-up ratio due to voltage stress to be clamped. An auxiliary switch instead of a both a transformer and a parallel-input/series-output (PISO) boost diode enables all switches to be turned on under ZVS configuration. Since the voltage spike across the switch is conditions. The zero-current turn-off of the secondary VDR limited to the output voltage of the boost converter, no alleviates its reverse-recovery losses.

Journal of Engineering Science and Technology Vol. 12, No. 12 (2017) 3344 - 3357 © School of Engineering, Taylor’s University DESIGN AND SIMULATION OF A HIGH PERFORMANCE CMOS VOLTAGE DOUBLERS USING CHARGE REUSE TECHNIQUE SHAMIL H. HUSSEIN Dept. of Electrical Engineering, College of Engineering, University of Mosul, Mosul, Iraq E-mail: [email protected] Abstract Voltage doubler (VD) structure plays an important role in charge pump (CP) circuits. It provides a voltages that is higher than the voltage of the power supply or a voltage of reverse polarity. In many applications such as the power IC and switched-capacitor transformers. This paper presents the design and analysis for VD using charge reuse technique CMOS 0.35µm tech. with high performance. Bootstrapped and charge reuse techniques is used to improve performance of integrated VD. Charge reusing method is based on equalizing the voltages of the pumping capacitances in each stage of CP. As a consequence, it reduces the load independent losses, improve the efficiency. Simulation using Orcad is applied for various VD structures shows improvement in charge reuse technique compared with existing counterpart. The results obtained show that the VD can be used in a wide band frequencies (0-100 MHz) or greater. The charge reuse VD circuit provided a good efficiency about (87.6%) and (83.5%) for one stage and two stage respectively at pump capacitance of 57pf, load current of 1mA, frequency of 10 MHz and supply voltage is 3.5 V compared with one stage and two stage of a latched VD are (85.4%) and (80%) respectively. -
HIGH VOLTAGE DC up to 2 KV from AC by USING CAPACITORS and DIODES in LADDER NETWORK Mr
[Prasad * et al., 5(6): June, 2018] ISSN: 2349-5197 Impact Factor: 3.765 INTERNATIONAL JOURNAL OF RESEARCH SCIENCE & MANAGEMENT HIGH VOLTAGE DC UP TO 2 KV FROM AC BY USING CAPACITORS AND DIODES IN LADDER NETWORK Mr. A. Raghavendra Prasad, Mr.K.Rajasekhara Reddy & Mr.M.Siva sankar Asst. Prof., Santhiram Engineering college, Nandyal Asst. Prof., Santhiram Engineering college, Nandyal Asst. Prof., Santhiram Engineering college, Nandyal DOI: 10.5281/zenodo.1291902 Abstract The aim of this project is designed to develop a high voltage DC around 2KV from a supply source of 230V AC using the capacitors and diodes in a ladder network based on voltage multiplier concept. The method for stepping up the voltage is commonly done by a step-up transformer. The output of the secondary of the step up transformer increases the voltage and decreases the current. The other method for stepping up the voltage is a voltage multiplier but from AC to DC. Voltage multipliers are primarily used to develop high voltages where low current is required. This project describes the concept to develop high voltage DC (even till 10KV output and beyond) from a single phase AC. For safety reasons our project restricts the multiplication factor to 8 such that the output would be within 2KV. This concept of generation is used in electronic appliances like the CRT’s, TV Picture tubes, oscilloscope and also used in industrial applications. The design of the circuit involves voltage multiplier, whose principle is to go on doubling the voltage for each stage. Thus, the output from an 8 stage voltage multiplier can generate up to 2KV. -

Power management of IoT nodes represents a challenging task, especially when the output of the energy harvester is in the order of few hundreds of millivolts. In these applications, the power management section can be profitably implemented, exploiting CPs. Indeed, presently, many different CP topologies have been presented in literature. Finally, a data-driven comparison is also provided, allowing for quantitative insight into the state-of-the-art of integrated CPs. Keywords: charge pump (CP); Dickson charge pump; energy harvesting; IoT node; power management; switched-capacitors boost converter 1. Introduction The Internet of Things (IoT) paradigm is expected to have a pervasive impact in the next years. The ubiquitous character of IoT nodes implies that they must be untethered and energy autonomous. In IoT nodes, power-autonomy is achieved by scavenging energy from the ambient using transducers, such as photovoltaic (PV) cells, thermoelectric generators (TEG), and vibration sensors [1–4]. -

A conventional symmetrical voltage multiplier (SVM) has much better performance, when compared with its half-wave counterpart. However, it requires a high-voltage transformer (HVT) with center-tapped secondary to perform its push pull kind of operation. The design of an HVT with center-tapped secondary is relatively complex. This paper proposes a hybrid SVM (HSVM) for dc high-voltage applications. The multiplier is formed by cascading a diode-bridge rectifier and an SVM with diode-bridge rectifier as the first stage of multiplier. The proposed topology saves two high-voltage capacitors and requires only one secondary winding of HVT. Besides, it has lesser voltage drop and faster transient response at start-up, when compared with conventional SVM. The feasibility of the proposed HSVM is validated both by simulation and experimental results of a laboratory scaled-down prototype.

An Altair Company Voltage Doubler Voltage doubler is the circuit where we get the twice of the input voltage, like if we supply 10v voltage, we will get 20 volt at the output. Generally transformers are there to step-up or step-down the voltage, but sometimes transformers are not feasible because of their size and cost. So here is the quick, easy and practical solution to double the voltage. • ACTIVATE solidThinking © 2017 solidThinking, Inc. Proprietary and Confidential. All rights reserved. An Altair Company Full Wave Voltage Doubler A Full wave voltage doubler is a voltage multiplier with a multiplication factor of two. A full wave voltage doubler is shown below. When the secondary voltage is positive, the first diode D is forward-biased and the primary capacitor C charges to approximately Vp. During the negative half- cycle, the secondary diode D is forward-biased and the secondary capacitor C charges to approximately Vp. The output voltage, 2Vp, is taken across the two capacitors in series. • ACTIVATE solidThinking © 2017 solidThinking, Inc. Proprietary and Confidential. All rights reserved.

An Altair Company By reversing the direction of the diodes and capacitors in the circuit we can also reverse the direction of the output voltage creating a negative voltage output. Also, if we connected the output of one multiplying circuit onto the input of another (cascading), we can continue to increase the DC output voltage in integer steps to produce voltage triplers, or voltage quadruplers circuits.
