Thyristor Over Voltage Protection
Thyristor Over Voltage Protection SCRs can be employed for protecting other equipment from over-voltages owing to their fast switching action. The SCR employed for protection is connected in parallel with the load. Whenever the voltage exceeds a specified limit, the gate of the SCR will get energized and trigger the SCR. A large current will … Continue reading “Thyristor Over Voltage Protection”
