    摘要: On end of a reactor (L1) is connected to a positive electrode of a battery (B1) and the other end is connected to a power line via a transistor (Q1) and to the ground via a transistor (Q2). By PWM control of the transistors (Q1, Q2), an arbitrary increased voltage is obtained in the power line. It is possible to obtain an optimal inverter input voltage (power line voltage) according to the motor drive state, thereby increasing efficiency. Thus, it is possible to optimize the inverter input voltage according to the motor drive condition.

    摘要: A power plant outputs motive power by driving a motor (22) using electric power from a direct-current power source (32). When the direct-current power source (32) has a low temperature, the direct-current power source is rapidly heated, whereby the performance can fully be demonstrated. In the power plant in which a capacitor (30) is installed so as to connect a positive electrode bus (26) and a negative electrode bus (28) of an inverter circuit (24) and the direct-current power source (32) is also installed so as to connect the negative electrode bus (28) of the inverter circuit (24) and a neutral point of the motor (22), when a power source temperature (Tb) of the direct-current power source (32) detected by a temperature sensor (50) is less than or equal to a threshold temperature (Tblow) at which supply of required electric power to the motor (22) is possible, an electronic control unit (40) sets a voltage between terminals of the capacitor (30) higher than normal and also sets a frequency of a carrier wave lower than normal, and performs switching control of transistors (T1 to T6) Thus, a ripple of a neutral point current which flows into the direct-current power source (32) can be increased, whereby it is possible to promote calorification of the direct current power source (32).

    摘要: In regenerative braking mode, an inverter converts, according to PWMC signal from a control unit, an AC voltage generated by a motor into a DC voltage to supply the converted DC voltage to an up-converter which down-converts the DC voltage to charge a DC power supply. The control unit receives voltage V2 from a voltage sensor to stop the up-converter if voltage V2 is higher than a predetermined value. The control unit further receives voltage Vf from a voltage sensor that is applied to a DC/DC converter and stops the up-converter if voltage Vf is higher than a predetermined value. Moreover, the control unit receives voltage V1 of the DC power supply from a voltage sensor to stop the up-converter if voltage V1 does not match voltage V2.
