Abstract :
The mechanism of zero current switching and zero voltage switching is analyzed. The concept of a source reactance lossless switch (SRLS) is proposed. The switch can be implemented in an SRLS voltage rectifier and an SRLS current rectifier. Using the SRLS technique, several DC-to-DC resonant converters with constant switching frequency control are proposed, in which zero current switching and/or zero voltage switching can be maintained from full load to no load. Steady-state analysis is presented for two basic topologies, the parallel-SRLS converter and series-SRLS converter. Experimental results are presented to verify the analysis
