Analysis and Design of a Passive Lossless Snubber in the Two-Inductor Boost Converter with a Variable Input Voltage
Abstract
This paper offers a detailed analysis of the non-dissipative snubbers for the hard-switched two-inductor boost converter fed from a sinusoidally modulated two-phase synchronous buck converter. The state analyses and the theoretical waveforms are provided for the three active operation modes of the snubber circuit. The set of border conditions in terms of the buck stage duty ratio for each operation mode is explicitly established. The experimental waveforms are also provided to validate the theoretical analysis.
