Systems and methods for limiting voltage on an auxiliary bus are described. The voltage-limited auxiliary bus may be comprised of a DC auxiliary bus comprised of a positive conductor and a negative conductor; a chopper, wherein the chopper is normally in a non-conducting state; a resistor in series with the chopper, wherein the chopper and the resistor are connected between the positive conductor and the negative conductor of the DC auxiliary bus; and a chopper control, wherein an overvoltage on the DC auxiliary bus causes the chopper control to cause the chopper to begin conducting and the conducting limits the voltage on the DC auxiliary bus and dissipates energy from the overvoltage.
