Controlled half-wave rectifier
Rectifier circuits may be single-phase or multi-phase. Most low power rectifiers for domestic equipment are single-phase, but three-phase rectification is very important for industrial applications and for the transmission of energy as DC (HVDC). In half-wave rectification of a single-phase supply, either the positive or negati… Rectifier circuits may be single-phase or multi-phase. Most low power rectifiers for domestic equipment are single-phase, but three-phase rectification is very important for industrial applications and for the transmission of energy as DC (HVDC). In half-wave rectification of a single-phase supply, either the positive or negati… WebThrough control of the firing angle, the average power delivered to the load can thus be controlled. With an AC voltage source, the SCR acts as a controlled half-wave rectifier, since it will block both the positive and the negative half-cycles until a positive control signal is applied to the gate.
