There are a number of different types of inverters but we will be discussing the type that is used to control electric motors in electrical engineering. These can also be known as AC drives, variable speed drives (VSD), and variable frequency drives (VFD).

What is a single phase induction motor?

The single-phase induction motor is a permanent split phase motor. Each of the main and auxiliary windings of the motor are supplied with voltages, which are phase shifted by 90° with respect to each other via an H-bridge.

What is the purpose of an inverter drive?

The purpose of an inverter drive is to convert AC mains (single-phase or three-phase) into a smoothed DC (direct current) supply to operate a motor. Inverters also introduce the ability to control speeds, acceleration and deacceleration time, braking methods, and torque.

How to control the speed of a single-phase induction motor?

The speed of single-phase induction motors can be controlled by either voltage control or frequency control. In voltage control, the voltage applied to main winding is kept constant but the voltage applied to the auxiliary winding is varied from 100 to 0%. The phase difference between the main and auxiliary winding is fixed at 90°.
