Power converter for engine generator

摘要

A power converter for an engine generator includes an insulative support that receives and supports circuit components for converting incoming AC power to desired power, such as power suitable for a welding application. One or more rectifier modules are provided that are received and supported by the support. Three such modules may be provided for receiving three phase power from a generator. DC power from the rectifier module is applied to DC bus plates. The plates may be coupled to capacitors. A power conversion circuit, such as a buck converter, is coupled to the DC bus plates to convert the DC power to output power.

1. A power converter comprising:
an insulative support; a rectifier module coupled to and supported by the insulative support, the rectifier module configured to receive AC power from a source; plate-like DC bus elements disposed in the insulative support and separated from one another by an insulative plate, the DC bus elements receiving DC power from the rectifier module; a power converter circuit supported by the insulative support and contacting the DC bus elements to receive the DC power and to convert the DC power to a desired output power; and a drive circuit board supported by the insulative support and coupled to the power converter circuit to command operation of the power converter circuit during operation.
