Single Phase Half Controlled Bridge Circuit
Single Phase Half Control Bridge with circuit details. It has two SCR’s T1(SCR1) and T2(SCR2) and two diodes D1 and D2. During the positive half-cycle of the ac supply, SCR T1 and diode D1 are forward biased. When the SCR T1 is turned-on at a firing angle alpha, supply voltage Vs appears across the load, i.e Vo Vs. The load current i0 flows through the path L-T1-load-D1-N.
During the negative half cycle of the ac supply, SCR-D2 and diode D2 are forward biased. When SCR T2 is turned on at a firing angle, the current would flows through the path N-T2-load-D2-L. This load current is continuous until the SCR T2 is turned off by reversal of supply voltage. Then T1 is triggered again and complete cycle repeats from pulse circuit.
