Power converter circuit board
First Claim
1. A circuit board, comprising:
- a substrate having a main layer including an electrically conductive portion and an electrically nonconductive portion adjacent the electrically conductive portion, the substrate having first and second opposite faces wherein the electrically conductive and nonconductive portions extend substantially an entire distance from the first face to the second face and further including a layer of insulating material disposed on a first side of the electrically conductive portion and an electrically conductive component in contact with the layer of insulating material; and
means extending through the layer of insulating material for coupling the electrically conductive component to the electrically conductive portion of the substrate.

Abstract
Prior power converters have utilized discrete components mounted on circuit boards of different design. Failure of one or more of the components requires the components to be separately tested to determine which is faulty. The faulty component or the board containing same must then be replaced. This results in significant down time for the inverter and can require stocking of a large number of specialized boards. In order to overcome these problems, an inverter is assembled using a series of circuit boards of standardized type. Each circuit board includes separate layers which interconnect components mounted thereon together with a heat exchanger which cools high power components. When a malfunction of a component occurs, the entire board may be replaced so that inverter down time is minimized. Also, the use of standardized boards reduces stocking requirements and inventory costs.
