ABSTRACT:
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.
