Inverter-driven rotating machine system, rotating machine and inverter used in the same and electric vehicle using the same

摘要

The present invention provides an inverter-driven rotating machine system improved in insulation reliability, a rotating machine and inverter used in the system and an electric vehicle using the system. Three-phase AC electric power of the inverter INV is supplied to a rear motor generator (RMG) by using a cable (CA1). One end of an additional cable (CA2) is connected to rotating machine terminals, namely motor input terminals (IT1) of a motor case (RMG-C). The other end is connected to fixed voltage terminals, namely inverter additional terminals (AT1) on an outer case (INV-C) of the inverter (INV) via resistors (R).
