A Switched Reluctance Motor with its high starting torque, high efficiency, simple speed control, and the lack of any back EMF makes it an excellent option for electric vehicles but the need for position and current sensing and its nonlinear inductance profile makes driving it a challenge. In this paper, various converter designs are investigated to drive the motor and a comparison is carried out between R-Dump, C Dump, and Asymmetric bridge converters where asymmetric bridge converter was deemed suitable to carry out further work. Using a MOSFET as the switching element and an ATmega328p microcontroller for control, an asymmetric bridge converter is constructed utilizing AS5600 and ACS712 to sense position and current.
