WebThis page will discuss basic triacs and SCRs. A triac is a bidirectional, three-terminal dual, back-to-back Thyristor (SCR) switch. This device can switch the current in either direction by applying a small current of either polarity between the gate and main terminal two. The triac is fabricated by integrating two Thyristors in an inverse ... The Silicon-Controlled Rectifier (SCR) SCR Conduction. If an SCR’s gate is left floating (disconnected), it behaves exactly as a Shockley diode. It may be latched by breakover voltage or by exceeding the critical rate of voltage rise between anode and cathode, just as with the Shockley diode. Meer weergeven The progression from Shockley diode to SCR is achieved with one small addition, actually nothing more than a third wire connection to the existing PNPN structure: (Figure below) Meer weergeven This method of securing SCR conduction is called triggering or firing, and it is by far the most common way that SCRs are latched in actual practice. In fact, SCRs are usually … Meer weergeven If an SCRs gate is left floating (disconnected), it behaves exactly as a Shockley diode. It may be latched by breakover voltage or by exceeding the critical rate of … Meer weergeven It should be mentioned that SCRs may sometimes be turned off by directly shorting their gate and cathode terminals together, or by reverse-triggering the gate with a … Meer weergeven
