    • A control device generates, upon receiving an instruction to start engine while drive wheels of a hybrid vehicle are driven by a motor generator, a signal to output the signal to a voltage step-up converter, and thereby drives and controls the voltage step-up converter to step up a DC voltage that is output from a battery to a maximum voltage of a motor drive apparatus. Then, the control device generates, when an output voltage of the voltage step-up converter reaches the maximum voltage, a signal to output the generated signal to an inverter. Accordingly, the inverter is driven and controlled to drive motor generator in powering mode.
    • 控制装置在通过电动发电机驱动混合动力汽车的驱动轮的状态下接收到起动发动机的指示时,产生将该信号输出到升压转换器的信号,从而驱动并控制升压 转换器将从电池输出的直流电压升高到电动机驱动装置的最大电压。 然后,当升压转换器的输出电压达到最大电压时,控制装置产生将产生的信号输出到逆变器的信号。 因此,驱动和控制逆变器以驱动电动发电机的上电模式。

    • A control device (30) calculates an upper limit value of a duty ratio (DR_Ulim) according to a voltage (Vm) from a voltage sensor (13) and a threshold voltage (OVb) when an overvoltage is determined to have been applied to a battery (B), and determines a duty ratio (DR) for providing switching control to NPN transistors (Q1, Q2) in a range lower than the calculated upper limit value of the duty ratio (DR_Ulim). The control device (30) uses the determined duty ratio (DR) to provide switching control to the NPN transistors (Q1, Q2). Then, an up-convener (12) converts a direct current voltage (Vb) from the battery (B) into the output voltage (Vm) such that an overvoltage is not applied to the battery (B).
    • 控制装置(30)根据来自电压传感器(13)的电压(Vm)和当将过电压确定为施加到电压传感器(13)时的阈值电压(OVb))来计算占空比(DR_Ulim)的上限值 电池(B),并且确定用于在低于所计算的占空比的上限值(DR_Ulim)的范围内向NPN晶体管(Q1,Q2)提供开关控制的占空比(DR)。 控制装置(30)使用确定的占空比(DR)来向NPN晶体管(Q1,Q2)提供开关控制。 然后,上升电路(12)将来自电池(B)的直流电压(Vb)转换为输出电压(Vm),使得不向电池(B)施加过电压。
