The trend in telecom power supplies is towards increasing power density. The drive for high power density in switch mode power supplies is pushing high switching frequency. This increase in switching frequency is limited by switching losses. To minimize switching loss, soft switching techniques such as zero voltage switching (ZVS) or zero current switching (ZCS) are adapted for high switching frequency...
