| Abstract |
Many research activities have been caried out on converter topologies using resonant elements to achieve soft switching. Some dc to dc converters use the inverter legs with resonant commutation to attain zero-voltage-switching. It is interesting to look at the behaviour of IGBTs at zero-voltage-switching because they are displacing bipolar transistors. In this paper, measured energy losses of a 50A/1000V IGBT at hard and zero-voltage-switching are used to design different converters with hard and resonant commutation. Experimental results of these converters are presented. A comparison of the component values shows the advantages and disadvantages of the resonant commutation in an inverter leg. |
