Single phase induction motor solid state drive using PWM technique / Mohd Edfarizal Ab. Rahim

This paper presents torque speed in single phase AC induction motor using PWM inverter. Nowadays AC induction motors are widely used in home appliances and other multipurpose instruments. An ATmega328 microcontroller (arduino uno) is used to generate the desire pulse width modulation (PWM) to optocouplers. Optocouplers function is like a driver to isolate the triggering pulse for buffering and sending to inverter where it will control the Hiridge inverter. Four IRF740 (power MOSFET) used to perform H*ridge inverter [] and 240 Volt DC voltage supply to this inverter then due this inverter circuit it converted to AC voltage to fed induction motor. The final output will be observed by measuring the rotor speed (rad/s) and the electromagnetic torque (Nm). The simulation is done using matlab/simulink and Psim.
