This paper presents a comparative harmonic analysis between a ZCS- QRC and ZVS-QRC topologies fed dc drive that uses a genetic fuzzy controller. The advantages of the different topologies employing MOSFET’s are presented. This operation employing genetic fuzzy controller can reduce the harmonic distortion and improves the performance of the drive when compared with the conventional control methods. The main objective of this work is to obtain reduced transient response, reduced switching stresses and switching losses which in turn enhances the efficiency and commutation capability of motor.
