Excitation of the resonant loads with the multi-vector synthesized si-nusoidal voltage decreases conduction losses and improves reliability
Main Article Content
Abstract
A method of DC/AC conversion based on the multi-vector synthesis of the sinusoidal voltage with the sequential elimination of unwanted harmonics in the output voltage and current resulting in lower power dissipation especially for the resonant loads is discussed. Simulation results of the standard 50% duty cycle operation approach and the proposed multi-vector topology are compared and linked to the temperature related characteristics of the MOSFET switches and resulting life expectancy of the DC/AC inverter.
