Abstract :
A comparison study was conducted to characterize the loss mechanisms, component stresses, and overall efficiencies of a group of voltage mode soft switching PWM methods including two improvement circuits developed at UCI. All soft switching methods in the selected group allow zero voltage turn-on and turn-off of the main switch and utilize a single auxiliary switch with some resonant components. Advantages and disadvantages were identified for each method. Experimental verification for each soft switching method were provided
