  • Introduction What Is a Polymer Capacitor?
    ECAS series (polymer-type aluminum electrolytic capacitor) No. C2T2CPS-063 Introduction If you take a look at the main board of an electronic device such as a personal computer, you’re likely to see some of the six types of capacitors shown below (Fig. 1). Common types of capacitors include tantalum electrolytic capacitors (MnO2 type and polymer type), aluminum electrolytic capacitors (electrolyte can type, polymer can type, and chip type), and MLCC. Figure 1. Main Types of Capacitors What Is a Polymer Capacitor? There are many other types of capacitors, such as film capacitors and niobium capacitors, but here we will describe polymer capacitors, a type of capacitor produced by Murata among others. In both tantalum electrolytic capacitors and aluminum electrolytic capacitors, a polymer capacitor is a type of electrolytic capacitor in which a conductive polymer is used as the cathode. In a polymer-type aluminum electrolytic capacitor, the anode is made of aluminum foil and the cathode is made of a conductive polymer. In a polymer-type tantalum electrolytic capacitor, the anode is made of the metal tantalum and the cathode is made of a conductive polymer. Figure 2 shows an example of this structure. Figure 2. Example of Structure of Conductive Polymer Aluminum Capacitor In conventional electrolytic capacitors, an electrolyte (electrolytic solution) or manganese dioxide (MnO2) was used as the cathode. Using a conductive polymer instead provides many advantages, making it possible to achieve a lower equivalent series resistance (ESR), more stable thermal characteristics, improved safety, and longer service life. As can be seen in Fig. 1, polymer capacitors have lower ESR than conventional electrolytic Copyright © muRata Manufacturing Co., Ltd.

Different technologies are used in high-voltage capacitor manufacturing process, and at all stages of this process polymeric films must be used, along with an encapsulating material, which can be either liquid, solid or gaseous. These materials play major roles in the lifespan and reliability of components.

  • TRIAC Overvoltage Protection Using a Transil™
    AN1966 Application note TRIAC overvoltage protection using a Transil™ Introduction In most of their applications, TRIACs are directly exposed to overvoltages coming from the mains, as described in IEC 61000-4-5 or IEC 61000-4-4 standards. When TRIACs are used to drive resistive loads (ex: temperature regulation), it is essential to provide them with efficient overvoltage protection to prevent any turn-on in breakover mode that could lead to device damage. A traditional method to clamp the voltage is to use a varistor in parallel across the TRIAC. But with high power loads (a few kW), the current through the varistor is very high in case of surge voltages (a few hundred amperes). The varistor is then not efficient enough, due to its dynamic resistor, to limit the TRIAC voltage to a low value. We present here a solution that can be used for these kinds of applications and also for all applications where TRIAC voltage protection is required. It should be noted that the overvoltages could also come from the overvoltages that appear at device turn-off due to the TRIAC holding current. This phenomenon occurs mainly with TRIACs controlling low rms current (15-50 mA), high inductive loads like valves. For more information about such behavior, please refer to AN1172. Contents 1 Why overvoltage protection is required . 2 2 Overvoltage protection solution . 3 3 Transil choice for efficient TRIAC voltage protection . 6 3.1 Normal operation: check VRM voltage . 6 3.2 Surge voltage clamping: check max VCL voltage . 6 4 Experimental validation example . 8 5 Conclusion .

  • Triac Control with a Microcontroller Powered from a Positive Supply
    AN440 Application note Triac control with a microcontroller powered from a positive supply Introduction This application note explains how to implement a control circuit to drive an AC switch (Triac, ACS or ACST) in case the microcontroller unit (MCU) is supplied with a positive voltage. The driving circuit will also depends on the kind of Triac used and also if other supplies (positive or negative) are available. We also deal about the case of insulated or non-insulated supplies. It is recommended to refer to AN4564 which explains why positive supplies are usually implemented and how simple solutions can be implemented to get a negative supply. Refer also to AN3168 for information about AC switch control circuits in case the microcontroller is supplied with a negative power supply. AN440 - Rev 4 - March 2020 www.st.com For further information contact your local STMicroelectronics sales office. AN440 Positive supply defintion and AC switch triggering quadrants 1 Positive supply defintion and AC switch triggering quadrants 1.1 Positive power supply A positive power supply is a supply where its reference level (VSS) is connected to the mains (line or neutral). The VDD level is then above the mains terminal as shown in Figure 1. If the supply is a 5 V power supply, then VDD is 5 V above the mains reference. This is why such a supply is called a positive supply (compared to a negative supply as shown in AN3168). Figure 1. Positive supply basic schematic 1.2 AC switch triggering quadrants To switch-on an AC switch, like any bipolar device, a gate current must be applied between its gate pin (G) and its drive reference terminal (refer also to AN3168).

  • Understanding Polymer and Hybrid Capacitors Advanced Capacitors Based on Conductive Polymers Maximize Performance and Reliability
    WHITE PAPER Understanding Polymer and Hybrid Capacitors Advanced capacitors based on conductive polymers maximize performance and reliability The various polymer and hybrid capacitors have distinct sweet spots in terms of their ideal voltages, frequency characteristics, environmental conditions and other application requirements. In this paper, we’ll show you how to identify the best uses for each type of advanced capacitor. We’ll also highlight specific applications in which a polymer or hybrid capacitor will outperform traditional electrolytic or even ceramic capacitors. POLYMER CAPACITOR VARIETIES Polymer capacitors come in four main varieties, including the hybrid. Each type has different electrolytic and electrode Hybrid capacitor technology combines the performance benefits of materials, packaging and application targets: electrolytic and polymer capacitors. • Layered polymer aluminum capacitors use conductive Capacitors may seem simple enough, but specifying them has polymer as the electrolyte and have an aluminum cathode actually grown more complex in recent years. The reason why (see Figure 1). Depending on the specific model, these comes down to freedom of choice. The universe of capacitors capacitors cover a voltage range from 2-25V and offer has expanded greatly over the past few years, in large part capacitances between 2.2-560µF. The distinguishing because of capacitor designs that take advantage of advances electrical characteristic of these polymer capacitors is in conductive polymers. their extremely low equivalent series resistance (ESR). For example, some of our SP-Cap™ polymer capacitors have These advanced capacitors sometimes use conductive polymers ESR values as low as 3mΩ, which is among the lowest in to form the entire electrolyte. Or the conductive polymers can be used in conjunction with a liquid electrolyte in a design known as a hybrid capacitor.

  • AN3168 Non-Insulated SCR / Triac Control Circuits
    AN3168 Application note Non-insulated SCR / Triac control circuits Introduction In alternating current applications the direct current power supply for low-voltage electronic devices (MCU, LEDs, optocouplers, Triacs and so on) can be provided using one of several different circuits. There are traditionally two major types of power supplies used in appliances, capacitive power supply and linear power supply using a step-down transformer. Today, designers are using more and more switches mode power supplies (SMPS) to achieve higher output current levels and especially lower standby power consumption. The power supply choice is a trade-off between several parameters. These are the cost, the required power, the output voltage level and polarity, the standby power consumption and the necessity or not of an electrical insulation between the mains and the low output DC voltage. This application note considers only non-insulated power supplies. After a brief description of the triggering quadrants and key parameters for SCR, Triac, ACS and ACST, the usual control circuits are described according to the output voltage polarity of the power supply. Finally, some examples of negative power supply circuits are introduced.
