Abstract
Prior power converters have utilized discrete components mounted on circuit boards of differing designs. Failure of one or more of the components requires testing each component to determine which is faulty. The faulty component must then be replaced. This results in significant down time for the inverter and can require stocking a large number of specialized boards. In order to overcome these problems, an inverter is assembled using modular circuit boards. Each circuit board includes components mounted on a multilayer substrate and a heat exchanger which cools high power components. When a malfunction of a component occurs, the entire board containing the failed component may be readily replaced so that inverter down time is minimized. The use of modular circuit boards also reduces stocking requirements and inventory costs.
