Comparison of experimental losses among six different topologies for a 1.6 kW boost converter, using IGBTs

This paper presents a comparative analysis of experimental losses between a new ZCS-PWM boost converter and five different boost topologies, using IGBTs, rated at 1.6 kW and operating at 20 kHz. The advantages of the new ZCS-PWM technique employing IGBTs are presented. This new ZCS operation can reduce the average total power dissipation in the devices, practically by half, when compared with the hard-switching method. This new ZCS-PWM boost converter is suitable for high power applications using IGBTs in power factor correction. The principle of operation, experimental results, and comparative analysis of the new ZCS-PWM boost converter are also provided.<<ETX>>
