Power inverter
First Claim
1. A power inverter comprising:
- a power module for converting direct-current to alternative current;
a gate drive circuit board for supplying switching power to said power module;
a rotating electric machine control circuit board for supplying a signal for controlling an electric rotating machine to said gate drive circuit board;
a smoothing capacitor module connected in parallel electrically to said power module and at the side of a battery of said power module;
a housing for storing said power module, said gate drive circuit board, said rotating electric machine control circuit board and said smoothing capacitor module; and
an active discharge circuit formed on a board different from said rotating electric machine control circuit board for discharging charge stored in said smoothing capacitor module,wherein said power module is arranged at one side of a storage area of said housing;
said smoothing capacitor module is arranged at another side of the storage area of said housing; and
said active discharge circuit is arranged rather than said power module at a side nearer said smoothing capacitor module.

Abstract
A power inverter comprises a power module connected at least to a rotating electric machine, a gate drive circuit board which supplies switching power to the power module, and a rotating electric machine control circuit board which supplies a signal for controlling the waveform of the switching power to the gate drive circuit board. A noise reduction board is formed on a board different from the rotating electric machine control circuit board. The configuration of the noise reduction board is such that various signals for forming a signal for controlling the waveform of the switching power by means of the rotating electric machine control circuit board are inputted through the noise reduction board to the rotating electric machine control circuit board.
