Increasing inverter reactor efficiency

Increasing inverter reactor efficiency MH&W International Corp announces New Ellipse Cores from Chang Sung Corp. Ellipse cores are an improvement in their MegaFlux block cores to increase efficiency of the smoothing chokes (Reactors) in inverters. The improvement in the block material consists of a 7.5 radius edge, creating an Ellipse core. This elliptical core design results in a wider window area and reduction in the number of turns due to higher DCB. The length of wire on one turn of the core decreases the length of wire by eight percent. This effectively decreases the copper loss and winding cost of the reactor. The DCB of the Reactor also increases over that of both MegaFlux block and High Flux Block cores, demonstrating a difference in the percent change of permeability of almost 10% at 200 Oe.
