Power MOSFETs offer many advantages over conventional bipolar transistors . These advantages include very fast switching 9 absence of second breakdown , wide safe operating area, extremely high gain, and high input impedance with low drive requirements. This paper presents an experemental DC to DC chopper circuit using parallel connected power MOSFETs for speed control of a seperately excited DC motor. The circuit operates from a 48 V battery and provides a maximum motoring current of 20 A .doi:10.21608/asat.1985.26625 fatcat:dgtz7eiojrce3k3n2xtq2hl324
