The Silicon Controlled Switch (SCS)
The Silicon Controlled Switch (SCS) is a four-layer semiconductor device that can be turned on and off by controlling the gate current. It is commonly used in power electronics applications due to its ability to handle high voltages and currents. The SCS is similar to a thyristor, but with an additional gate terminal.
The Turn-On Process
To turn on the SCS, two methods can be used: by applying a negative pulse to the anode gate and a positive pulse to the cathode gate.
Method 1: Negative Pulse to the Anode Gate
When a negative pulse is applied to the anode gate, it reduces the potential barrier between the p+ and n- regions, allowing the minority carriers (holes in this case) to flow towards the n- region. This results in the formation of a conducting path between the anode and cathode terminals.
Method 2: Positive Pulse to the Cathode Gate
Simultaneously, a positive pulse is applied to the cathode gate. This positive pulse attracts the minority carriers (electrons) towards the p+ region, creating a conducting path between the anode and cathode terminals.
Combined Effect
The combination of the negative pulse on the anode gate and the positive pulse on the cathode gate allows the SCS to be turned on. The negative pulse reduces the potential barrier, while the positive pulse attracts the minority carriers, resulting in the formation of a conducting path between the anode and cathode terminals.
Summary
In summary, the SCS can be turned on by applying a negative pulse to the anode gate and a positive pulse to the cathode gate. The negative pulse reduces the potential barrier, allowing the minority carriers to flow towards the n- region. Simultaneously, the positive pulse attracts the minority carriers towards the p+ region, creating a conducting path between the anode and cathode terminals. This combined effect enables the SCS to conduct current and be turned on.
