Controlling SCR Half-Wave Rectification

Thyristors, also called silicon controlled rectifiers (SCRs), are used to control current in a rectifier circuit. Like diodes, they let current pass from the anode to the cathode and block current in the opposite direction. Unlike a diode, a thyristor can be turned on with a gate terminal that receives a small current pulse....

Thyristors, also called silicon controlled rectifiers, or SCRs, are electronic devices used in light dimmers, motor speed controllers, and voltage regulators. Like a diode, a thyristor has an anode and a cathode, and conducts in only one direction. In fact, the schematic symbol for a thyristor resembles a diode, but with a third terminal represe...
