Abstract

A control circuit for a power converter is provided. The control circuit includes a pulse width modulator, a current feedback loop, a bus voltage feedforward path, and a logic circuit. The pulse width modulator generates a control signal for the power converter to regulate a load current. The current feedback loop controls the pulse width modulator to converge the load current to a demanded current. The bus voltage feedforward path measures a bus voltage supplied to the power converter at an input bus and, in combination with the current feedback loop, control the pulse width modulator to regulate the load current based on the bus voltage. The logic circuit collects load current measurements and determines, based at least partially thereon, a voltage variation event has occurred on the input bus, and disables the control signal for the power converter in response to determining the voltage variation event has occurred.
