    • In a vehicular electric system, a first motor driver device and a second motor driver device are connected in parallel to a DC power source. A first capacitor is provided to suppress variations in a voltage developed between the DC power source and the first motor driver device. A second capacitor is provided to suppress variations in a voltage developed between the DC power source and a second motor driver device. A resistor is connected in series to the second capacitor. A filter circuit is thus suppressed form resonance even when a frequency included in a ripple current outputted from an inverter circuit of the first motor driver device overlaps a resonance frequency of the filter circuit.

    • An inverter control circuit controls transistors based on comparison of a voltage command wave with a carrier wave, when a magnitude of a voltage vector is equal to or less than a peak value of the carrier wave. The voltage command wave is a wave, which is offset to a maximum value side from a reference potential of the carrier wave so that a maximum value of the voltage command wave equals a peak value of the carrier wave. The inverter control circuit makes an on-period of the transistor on a positive bus side longer than that of the transistor on a negative bus side by using the command voltage. The amount of electricity charged in a capacitor is reduced in comparison with a case in which the voltage command wave is used. Thus, thermal loss of a stator coil and a diode on the positive bus side is reduced.
    • 当电压矢量的大小等于或小于载波的峰值时,逆变器控制电路基于电压指令波与载波的比较来控制晶体管。 电压指令波是从载波的基准电位偏移到最大值侧的波,使得电压指令波的最大值等于载波的峰值。 逆变器控制电路通过使用指令电压使正的母线侧的晶体管的导通周期长于负母线侧的晶体管的导通周期。 与使用电压指令波的情况相比,电容器中充电的电量减少。 因此,正母线侧的定子线圈和二极管的热损耗降低。
