摘要：

A novel active snubber for the boost converter is presented in this paper. The main novelty in this solution is that auxiliary (snubber) switch takes part in energy transfer from source to output. Although equal currents do not flow through the boost and snubber switches they operate in parallel during most of the time they are turned on. Zero-voltage turn-off and zero-current turn-on for both switches, and reduced reverse-recovery-related losses in the boost switch and diode are achieved as well. Very simple and reliable control circuit is employed because nonisolated gate-drive signals are the same for both switches.
