摘要： A power inverter of the type used with hybrid electric vehicles having a circuit board with a power layer having a first and second section which are electrically separated using slits from each other on the power layer. A control circuit is connected to and powered by the first section of the power layer while a switching power supply is connected to and powered by the second section of the power layer. An electromagnetic filter is electrically connected between the sections of the power layer. This electromagnetic filter blocks high frequency noises of the type generated by the switching power supply while enabling the sections to be maintained at the same DC voltage level. Optionally, a ferrite covering is provided around a current bus bar of the power inverter to contain magnetic fields generated by current flow through the bus bar.

摘要： According to the invention, there is provided a water cooled inverter structure forming a plurality of shallow cavities and deep cavities in a housing, fixing a bottom surface of power semiconductor modules to shallow cavities to form a shallow water channel and directly cooling the power semiconductor modules using this shallow water channel. Since cooling water flows fast in the shallow water channel, it is possible to improve a cooling efficiency and also reduce pressure loss using a deep water channel with deep cavities. Furthermore, providing a plurality of cavities makes it possible to reduce a size of the power semiconductor modules and provide a plurality of power semiconductor modules, thus improving reliability. It is possible to place a control board below the water channel to thermally cut off the control board from the power semiconductor modules, which makes it possible to reduce temperature of a control circuit.
