Design and Implementation of Adaptive Parallel Resonant Converter in Variable Tank Parameters

Authors

Abstract

Abstract—Nowadays the use of switching converter systems are increasing. One of these converters is resonant converter which is more efficient than other converters. In this paper, the parallel resonant converter (PRC) is used. Because of environmental conditions, there is probably a variation in the resonance tank parameters values in resonant circuits. These variations occur due to variation in the resonance circuit impedance. The output voltage is strongly dependent on variation of the output load and the resonance tank parameters. Changing the resonance parameters will directly affect the output voltage. By using the mathematical relations, values of the resonance tank frequency and proper switching frequency are obtained. With partial changes in obtained frequency, output voltage is fixed. The main advantages of this design are recognizing proper resonance tank parameters, resonance frequency and switching frequency which depends on each circuit with unknown values. In proper searching method, there is more accurate regulation of obtained switching frequency. Other advantages include simple control algorithm which can be assembled with simple processor system. Experimental and simulation results presented in this paper show the benefits of proposed method.
