| Abstract |
Efficiency measurements on a three-level single-phase soft-switched converter are presented and show
a slightly improved efficiency compared with the hard-switched converter for output powers higher
than 25 % of rated power. The resonant converter uses Zero Voltage Switching (ZVS) and a simple
resonant circuit. Increased resonant converter efficiency enables a reduction in the semiconductor size
pr. watt output power or an increase the switching frequency. |
