Abstract
An overvoltage snubber circuit configured to receive an alternating current (AC) overvoltage includes a first rectifier configured to convert the AC overvoltage to a direct current (DC) overvoltage, a chopper circuit electrically connected to the first rectifier and configured to break up the DC overvoltage and to output a variable DC voltage, and a resistor electrically connected to the chopper circuit and configured to dissipate energy of the variable DC voltage.
