Induction motors with a single phase are commonly utilised in household goods and industrial control. Controlling the speed of these motors allows for multispeed and multifunctional operation. The variable speed drive of an induction motor utilising the frequency control approach is the subject of this research article. It is to build a solid-state control system that is both dependable and cost-effective for usage with fractional horse power motors. The proposed variable speed drive contains a power conversion section (AC to DC and DC to AC), which employs an IRF 840 N-channel MOSFET as the switching element. To give alternating current to the motor, four IRF 840 MOSFETS are employed as H-bridge inverters. In this drive, C124 transistors and MJE 13002 transistors are used as driver circuits to drive the H-bridge inverter. In this drive, there is two power supply. The frequency control circuit and driving circuit both need a 12 V power supply. For the H-bridge inverter, a 300 V power source is employed. The frequency is controlled by a pulse width modulation SG3525A IC in this drive. For altering the speed of an induction motor, the designed variable drive circuit has a frequency range of 16 Hz to 56 Hz at a constant voltage. The driving schemes of single-phase induction motors are discussed in this research study, as well as the principle actions of components utilized in variable speed drives, as well as the design calculations needed to build this drive, are supplied. Furthermore, the experimental testing of this drive when running a single-phase induction motor with a fractional horsepower is presented.
