Abstract
With the new developments in the field of power electronics, the industrial application demands the usage of power semiconductors with high-frequency switches (IGBT’S, MOSFET’s, GTO’s) and the usage of high-frequency passive devices which have resulted in the innovation of resonant power converters. These converters give the ability of soft-switching with improved current and voltage waveforms and higher power densities. Their key feature is the high frequency operation of the device with minimal losses and increases efficiency. Besides this, the size, weight and hence the cost of the converter also gets minimized. Comparing with the conventional hard switching devices, the above characteristics have given a path to the soft switching devices for various industrial applications. This paper provides a detailed comparison of various types of resonant converters, their topology with the basic principles, various disadvantages and advantages and choosing the most efficient resonant converter in terms of the various parameters defined.
