摘要: In this paper, a new isolated DC-DC boost converter based on three-state switching cell (3SSC) is proposed. The mentioned allows the use of only two windings in isolation transformer, as well as, series connection one DC current blocking capacitor to avoid its saturation. Other relevant characteristics are, voltage across controlled switches low, which utilization lower drain-to-source conduction resistances (RDSon) MOSFETs, and through autotransformer winding almost continuous minimizing hysteresis losses magnetic core. way, efficiency proposed high, it recommended for development power supplies using low sources commonly found renewable energy conversion systems batteries. was analyzed overlapping control signals or duty cycle higher than 0.5 operating mode (CCM). order verify feasibility topology; principle operation, theoretical analysis, experimental waveforms are shown lkW assembled prototype.
