Abstract
According to the present disclosure, there is provided an inexpensive power conversion system that can achieve loss reduction and space saving. The power conversion system includes: a power converter configured to convert direct-current power input from a direct-current power supply, into alternating-current power or direct-current power; a capacitor provided between a positive electrode direct-current line and a negative electrode direct-current line connected to input terminals of the power converter; a ground line provided with a first ground resistor and configured to connect the negative electrode direct-current line and a ground potential; a discharge line configured to connect the positive electrode direct-current line and the ground line on the ground potential side of the first ground resistor; and a discharge switch provided in the discharge line and configured to be turned on to discharge residual charges of the capacitor.
