Abstract:
A drive circuit includes a transient detector that includes a detector input to receive a loop error signal from a phased locked loop (PLL) and generates a transient detected output signal if a transient is detected in an alternating current (AC) input voltage. A controller includes a controller input to receive the transient detected output signal from the transient detector and a feedback input to sense the AC input voltage provided to a bridge circuit. The controller is configured to apply a PLL angle output signal from the PLL to control switch output signals to the bridge circuit if the transient detected output signal is not generated and configured to apply the AC input voltage sensed from the feedback input to control the switch output signals to the bridge circuit if the transient detected output signal is generated.

Claim (Index 12):
A system, comprising:\n a bridge circuit configured to rectify an alternating current (AC) input voltage into a direct current (DC) output voltage in response to switch output signals; a phased locked loop (PLL) that includes a PLL input to receive the AC input voltage, wherein the PLL is configured to generate a PLL angle output signal that represents a frequency of the AC input voltage and a loop error signal that represents a phase error between the AC input voltage and a locked PLL angle of the PLL; a transient detector that includes a detector input to receive the loop error signal from the PLL, wherein the transient detector is configured to compare the loop error signal to a threshold and to generate a transient detected output signal if the loop error signal exceeds the threshold; and a controller that includes a controller input to receive the transient detected output signal from the transient detector and a feedback input to sense the AC input voltage that is provided to the bridge circuit, wherein the controller is configured to apply the PLL angle output signal to control the switch output signals to the bridge circuit if the transient detected output signal is not generated and configured to apply the AC input voltage sensed from the feedback input to control the switch output signals to the bridge circuit if the transient detected output signal is generated.
