Implementation of FM-ZCS-Quasi Resonant Converter Fed DC Servo Drive
This paper deals with the implementation of FM-ZCS-QRC fed DC servo drive using micro controller. The salient feature of QRC is that the switching devices can be either switched on at zero voltage or switched off at zero current, so that switching losses are zero ideally, switching stresses are low, volumes are low and power density is high. This property imparts high efficiency and high power density to the converters. The output of QRC is regulated by varying the switching frequency of the converter. Hence it is called Frequency modulated Zero current/zero voltage switching quasi resonant converter. The present work deals with simulation and implementation of DC Servo motor fed from ZCS-QRC. Simulation results show that the ZCS-QRC’s have low total harmonic distortion. The ZCS-QRC operating in half wave and full wave modes are simulated and implemented successfully. The experimental results are compared with the simulation results. Keywords : Zero Current switching (ZCS), Quadratu...
