Abstract :
Paper clarifies the definition of control type soft switching and presents five characteristics for control type soft switching topologies. The theory of five characteristics is verified in the existing control type soft switching topologies, and a series of new control type soft switching topologies, such as buck, boost, buck-boost, cuk, zeta, sepic, flyback, and forward are constructed. A 200 kHz prototype of 48 V input, 19 V output, whose highest conversion efficiency is 96.1% is built to verify the theory of five characteristics for control type soft switching.
