ABSTRACT:
A single quadrant chopper timing control circuit is used with unidirectional power flow chopper arrangements in a power inverter to maintain current oscillation between positive and negative threshold levels of a hysteresis controller. The single quadrant chopper timing control circuit creates a mimic current when the current in the power inverter becomes zero or less. The mimic current allows the unidirectional power arrangement to continue oscillating so that there is little or no discontinuity in the timing. The device will continue to operate and provide a high bandwidth to ensure that the device will function during an overload or load dump condition.
