SOFT SWITCHING INVERTER USING A SOFT SWITCHING CONVERTER, CAPABLE OF MINIMIZING SWITCHING LOSS BY MINIMIZING THE OVERLAP AREA OF THE VOLTAGE AND THE CURRENT OF A SWITCHING DEVICE

摘要

PURPOSE: A soft switching inverter using a soft switching converter is provided to reduce the size and the weight of passive elements using converter and inverter circuits in a higher frequency region.;CONSTITUTION: A soft switching inverter includes a power supplying part(110), a direct current/direct current(DC/DC) converter part(120), a direct current/alternating current(DC/AC) inverter part(130), and a controlling part. The DC/DC converter part boosts a direct current voltage supplied from the power supplying part. An inductor(L1) is in parallel connection with a first resonance capacitor. A second switching element(S2) is in serial connection with a DC-link capacitor(C3).;COPYRIGHT KIPO 2011
