摘要：Resonant switching is preferred over hard switching to minimize the switching losses. Resonant switching DC-DC converters are attractive for power supply in many applications due to their distinct advantages such as high efficiency, high frequency operation, compact structure, low EMI, etc.as compared to hard-switched converters. The paper deals with design and simulation of ZCS-Quasi resonant converter fed DC servo drive using Matlab Simulink. The salient feature of QRC is that the switching devices can be either switched on at zero current or switched off at zero current, so that switching losses may be zero, with low switching stresses, low volumes and high power density. The output of QRC is regulated by varying the switching frequency of the converter.
