Systems and methods for limiting voltage on an auxiliary bus

Systems 100 and methods for limiting voltage on an auxiliary bus are described. The voltage-limited auxiliary bus may be comprised of a DC auxiliary bus 126 comprised of a positive conductor 1262 and a negative conductor 1264; a chopper 1282, wherein the chopper 1282 is normally in a non-conducting...

Zusammenfassung:	Systems 100 and methods for limiting voltage on an auxiliary bus are described. The voltage-limited auxiliary bus may be comprised of a DC auxiliary bus 126 comprised of a positive conductor 1262 and a negative conductor 1264; a chopper 1282, wherein the chopper 1282 is normally in a non-conducting state; a resistor 1284 in series with the chopper 1282, wherein the chopper 1282 and the resistor 1284 are connected between the positive conductor 1282 and the negative conductor 1264 of the DC auxiliary bus 126; and a chopper control 1286, wherein an overvoltage on the DC auxiliary bus 126 causes the chopper control 1286 to cause the chopper 1282 to begin conducting and the conducting limits the voltage on the DC auxiliary bus 126 and dissipates energy from the overvoltage.
