Resources and methods for learning about these subjects (list a few here, in preparation for your research): 1 Questions Question 1 All thyristor devices exhibit the property of hysteresis. From an electrical perspective, what is ”hysteresis”? How does this behavior differ from that of ”normal” active semiconductor components such as bipolar or field-effect transistors? file 01089 Question 2 What is required to make a Shockley diode or DIAC begin conducting current? What condition(s) have to be met in order for electrical conduction to occur through one of these devices? Also, explain what must be done to stop the flow of electric current through a Shockley diode or a DIAC. file 01090 Question 3 Silicon-controlled rectifiers (SCRs) may be modeled by the following transistor circuit. Explain how this circuit functions, in the presence of and absence of a ”triggering” voltage pulse at the gate terminal: Load Anode Gate Cathode file 01088 2 Question 4 Shown here is an illustration of a large ”stud mount” type of SCR, where the body is threaded so as to be fastened to a metal base like a bolt threads into a nut: With no test instrument other than a simple continuity tester (battery and light bulb connected in series, with two test leads), how could you determine the identities of the three terminals on this SCR? Hint: The threaded metal base of the SCR constitutes one of the three terminals.

  • Phase Control Using Thyristors
    Teccor® brand Thyristors AN1003 Phase Control Using Thyristors It is important to note that the circuit current is determined Introduction by the load and power source. For simplification, assume Due to high-volume production techniques, Thyristors the load is resistive; that is, both the voltage and current are now priced so that almost any electrical product can waveforms are identical. benefit from electronic control. A look at the fundamentals of SCR and Triac phase controls shows how this is possible. Full-wave Rectified Operation Voltage Applied to Load Output Power Characteristics Phase control is the most common form of Thyristor power control. The Thyristor is held in the off condition -- that is, all current flow in the circuit is blocked by the Thyristor except a minute leakage current. Then the Thyristor is triggered Delay (Triggering) Angle into an “on” condition by the control circuitry. Conduction Angle For full-wave AC control, a single Triac or two SCRs connected in inverse parallel may be used. One of two Figure AN1003.2 Sine Wave Showing Principles of Phase methods may be used for full-wave DC control -- a bridge Control rectifier formed by two SCRs or an SCR placed in series with a diode bridge as shown in Figure AN1003.1. Different loads respond to different characteristics of the AC waveform. For example, some are sensitive to average voltage, some to RMS voltage, and others to peak voltage. Various voltage characteristics are plotted against conduction angle for half- and full-wave phase control circuits in Figure AN1003.3 and Figure AN1003.4.

  • Rangkaian Dimmer Pengatur Iluminasi Lampu Pijar Berbasis Internally Triggered TRIAC
    Rangkaian Dimmer Pengatur Iluminasi Lampu Pijar Berbasis Internally Triggered TRIAC Herlan Briliant Adhi Prabowo Bidang Komputer Bidang Komputer Pusat Penelitian Informatika LIPI Pusat Penelitian Informatika LIPI [email protected] [email protected] Abstrak Salah satu implementasi piranti semikonduktor adalah untuk rangkaian dimmer yang dapat digunakan pada pengaturan iluminasi lampu pijar. Pengaturan iluminasi pada lampu AC memiliki kompleksitas yang berbeda dengan lampu dc. Metode yang digunakan adalah dengan pengaturan sudut phasa penyalaan gelombang AC dengan piranti semikonduktor sejenis TRIAC dan DIAC. Pada percobaan ini digunakan piranti Internally Triggered TRIAC sebagai inti rangkaian dimmer. Penelitian ini dilakukan untuk memperoleh sistem yang responsif terhadap iluminasi sebuah lampu pijar, melalui pengaturan Tegangan Root Mean Square. Dengan menggunakan Integrally Triggered Triac rangkaian dimmer memiliki respon yang signifikan terhadap pengaturan iluminasi lampu pijar. Kata kunci: TRIAC, dimmer, iluminasi, Lampu Pijar ruangan mendapat pencahayaan yang cukup, 1. Pendahuluan tidak berlebihan ataupun kekurangan yang dapat menimbulkan ketidaknyamanan. Pengaturan iluminasi cahaya lampu pijar Pengaturan iluminasi pada sebuah lampu pada sumber tegangan searah (DC/Direct dengan tegangan AC dipengaruhi oleh Current) cukup sederhana untuk impedansi lampu tersebut, dimana diimplementasikan hanya dengan pengaturan impedansi akan mempengaruhi, pengaturan tegangan menggunakan variabel arus, tegangan dan frekuensi
