Compact Inverter for Single-Phase Induction Motor

The developed compact frequency converter for a single-phase asynchronous motor is presented the paper. The use of classical frequency converters with the complex control system allows us to smoothly adjust a wide range of the motor speed with maintaining the stiffness of the mechanical characteristics. This converter is based on using semiconductor devices to control a single-phase asynchronous motor. The developed frequency converter has a low cost and simple design compared to previous frequency converters. Using the compact frequency converter for a single-phase induction motor, we can get better performance than with various methods of started induction motor at a low cost.
