Abstract
A DC to AC power inverter has an improved construction providing for substantially improved thermal disipation, reliability, and efficiency; the inverter has a unitary combination frame and heat diffuser with a pair of opposed U-shaped sections at right angles to each other and with a common base, a cover, a transformer, a primary internal heat sink inside of and on the frame, a plurality of power switches fastened on the internal heat sink, a printed circuit board fastened to and spaced from the heat sink with leads from the switches connected to the board, the transformer is fastened onto the frame in heat exchange relationship and part of the coil extends through the frame into an air passageway. All of the wiring access is on a field wiring end and the opposite end is a control end with the switches and circuit board; an improved arrangement of components and leads provides discrete separation of the high and low voltage components and leads. The inverter is extremely effective at heat disipation and has been UL tested and approved.
