WebIt is well known that the soft-switching techniques used in the conventional resonant SC converters, zero transition PWM SC converters and resonant-inductor-based SC converters are resonant soft-switching techniques, which will cause high resonant current spikes on the switches and increase the current stresses of the switches. WebThe characterization of soft-switching losses of modern high-voltage SiC MOSFETs is a difficult but necessary task in order to provide a sound basis for the accurate modelling of converter systems, such as medium-voltage-connected SolidState Transformers (SSTs), where soft-switching techniques are employed to achieve an improved converter ...
A State-of-the-Art Review on Soft-Switching Techniques for …
WebSoft switching techniques have been applied to develop a novel dc/dc power converter for feeding small loads (under 5 MW) with low cost and high reliability, from HVDC transmission lines. This dc/dc converter is connected in series with a pole of the HVDC transmission line. It drains energy to a dc capacitor through an air-core transformer. From this dc capacitor, … WebThe realization of soft-switching for both leading leg and lagging leg is proposed, based on which, soft-switching techniques for PWM full bridge converters can be classified into two kinds: zero-voltage-switching (ZVS) and zero-voltage and zero-current-switching (ZVZCS). The modulation strategies and topologies for the two kinds of soft ... can humans grow feathers
