Power Module, Power Converter Device, and Electrically Powered Vehicle

摘要

A power converter device includes a double-sided electrode module that converts direct current power to alternating current power, a heat dissipating base, a capacitor module, a positive electrode conductor plate, and a negative electrode conductor plate. In the heat dissipating base, heat dissipation surfaces, facing one another, of the double-sided electrode module facing to one another are held with insulation layers being present between the heat dissipating base, and the heat dissipation surfaces. The capacitor module constitutes a smoothing circuit for inhibiting fluctuation in DC voltage. The positive electrode conductor plate and the negative electrode conductor plate transmit electric power between the capacitor module and the double-sided electrode module.
