    摘要: The invention relates to a motor control apparatus and on-vehicle motor drive system which can easily protect components of an inverter 32 from overvoltage even if surplus power occurs in a generator 21 in a system without a battery between a generator and a motor.
    The inverter 32 converts the DC power generated by a generator 21 to AC power, and supplies it to an AC motor 40. A controller 100 controls DC-to-AC conversion in the inverter 32. Interruption means including an overvoltage detector 36 and a semiconductor switch 38 prevents the power generated by the generator 21 from being supplied to the inverter 32 when the inverter 32 is stopped.
