Abstract :
Efficiency and power density are usually two important goals regarding power converter design. The focus of this paper is to develop an evaluation procedure to investigate the relationship between efficiency, power density and switching frequency. Three-phase two-level PWM boost rectifier is used as an example. Estimated efficiency and converter weight changing along with switching frequency and power rating are shown. A comparison with a hardware prototype is carried out to verify the estimation procedure.
