Abstract:
PROBLEM TO BE SOLVED: To provide an on-vehicle motor compressor capable of increasing the range of an applicable vehicle type.SOLUTION: A current sensor 31 is provided between a connection terminal 22 connected with an on-vehicle power supply 10 and a filter circuit 28. A frequency of a ripple component of an input current of an inverter 24 is verified from a measurement current of the current sensor 31, and a control section 32 of the inverter 24 is formed to variably set a carrier frequency of the inverter 24 so as to avoid overlapping with the verified frequency.
