Single Phase AC

Single Phase, Phase Angle:
In phase angle control, each SCR of the back-to-back pair is turned on for a variable portion of the half-cycle that it conducts. Power is regulated by advancing or delaying the point at which the SCR is turned on within each half cycle. Light dimmers are an example of Phase-Angle control.
Single Phase, Zero Cross:
In zero-cross control, load power is turned ON and OFF only when instantaneous value of the sinusoidal waveform is zero. Load power is controlled by switching the SCRs “ON” for a number of complete electrical half-cycles, and then “OFF” for a number of complete electrical half-cycles.
