Single Phase Fully Controlled Bridge Power Circuit

Fully controlled bridge rectifier for a resistive load.  A fully-controlled circuit contains only thyristers (semiconductor or silicon controlled rectifiers.  SCR1 and SCR2  must be fired simultaneously during the positive half-wave of the source voltage VRs Rto allow conduction of current. Alternatively, SCR3 and SCR4 must be fired simultaneously during
