This proposed paper is to model and simulate the sensor less control of Brush less DC motor with four-switch three phase inverter. Here, a new structure of three phase inverter with reduced number of switches i.e. four-switch for BLDC drive is introduced to reduce the switching losses that occur in the six-switch method and eliminate the mechanical commutation. Conventionally used hall sensors for position detection increase the size of the motor and are temperature sensitive since they are mounted inside. So sensor is eliminated and the back emf method is adopted for switching. The zero-crossing point can be detected and it is used to commutate a motor thereby increasing the overall efficiency.
