Abstract
A phase controlled drive circuit includes a drive circuit operable to provide gate signals to an SCR bridge circuit and a phase control circuit. The phase control circuit includes a first phase generator operable to generate a first phase signal, and a second phase generator operable to generate a second phase signal. The second phase signal is periodically reset to an initial value. A drive circuit actuator in the phase control circuit is operable to place the drive circuit in a first activation state when a sum of the first and second phase signals exceeds a threshold value, and is further operable to place the drive circuit in a second activation state when the sum of the first and second phase signals is less than the threshold value.
