The IPM is provided to abut an upper surface of the bottom plate. The control substrate is a rectangular plate having mounted thereon a control circuit including electronic components such as a gate driver, a transformer and the like, and is provided above the IPM. The capacitor is accommodated in a housing in a substantially parallelepiped form. A reflector made of aluminum of high thermal reflectivity and high thermal conductivity is provided on the entire lower surface of the capacitor.

    摘要： A surge voltage generated by the switching operation of an IGBT element and voltage variation generated in an equivalent series resistance of a capacitor are superimposed on an input voltage of an inverter. The equivalent series resistance has a temperature dependence that a resistance value increases with a decrease in a capacitor temperature. The IGBT element has a temperature dependence that an element withstand voltage decreases with a decrease in an inverter temperature. When capacitor temperature is lower than a predetermined threshold value, a control device reduces an upper limit value of the input voltage by an amount corresponding to the voltage variation from its upper limit value at a high temperature, and controls a target voltage of a boost converter such that an output voltage does not exceed the upper limit value. Consequently, the allowable range of the surge voltage can be ensured.
