Abstract
A power conversion system including a DC main power supply for supplying a DC voltage, boosting circuits for performing a retrogression operation of boosting the DC voltage and comprising driving circuits, an inverter circuit for converting the DC voltage into an AC voltage, a motor/generator for receiving the AC voltage, and a control circuit for outputting a control signal to the driving circuits and stopping an operation of a faulty boosting circuit of the boosting circuits when one of the boosting circuits is faulty, for setting power control values depending on a number of remaining non-faulty boosting circuits of the boosting circuits, and for controlling the remaining non-faulty boosting circuits and the inverter circuit based on the power control values, wherein the inverter circuit and the boosting circuits perform a regeneration operation of supplying regeneration power to the DC main power supply, peripheral equipment, and/or a DC auxiliary power supply.
