Abstract :
Zero-current-transition (ZCT) PWM converters are conventional PWM converters that use an active auxiliary circuit to turn off the main power switch with zero current switching. In the paper, the general operating principles behind all ZCT-PWM converters are reviewed, and the operation and properties of specific boost converters are discussed. The strengths and weaknesses of each converter are stated and a new and improved ZCT-PWM boost converter is proposed and compared with the other converters. Experimental results that confirm the superior performance of the new proposed converter are presented
