Abstract
In this work, a novel driver circuit is designed for permanent split capacitor motors (PSC). With this driver circuit, semi-conductive technology is used in place of cumulative winding for this type of motors that are particularly used in kitchen exhaust fans. Developed circuit is controlled via PWM method. IGBT transistors are used for the power circuit. An optocoupler driver is designed and used in order to drive and trigger these IGBT transistors. Due to this reason, this work includes an electronic AC/AC chopper application that provides energy conservation and noise reduction by removing cumulative winding in currently used asynchronous motors with cumulative auxiliary winding stators and shaded pole motors.

Summary
Asynchronous motors are frequently used in industrial applications and residences, due to their user friendliness, simple design, being maintenance free and cheap. Single-phase asynchronous motors are commonly used in household appliances. PSC motors, split phase motors, permanent magnet synchronous motors and shaded-pole motors are among the most frequently used ones. The direct AC-AC converters have applications in various fields, such as AC motor drives, electronic transformers, switching AC adjustable sources, output voltage waveform restorers, etc [2]. A novel driver circuit is designed, which removes cumulative winding from PSCs that are used in kitchen exhaust fans. Semi-conductive material that is going to be used in speed control of asynchronous motors needs to be chosen properly. Signal that is applied to motor is used in Pulse Width Modulation (PWM) invertor form.
