Abstract

Translate Article

This paper presents a Single-Phase Induction Motor (SPIM) driven by a Single-Phase Matrix Converter (SPMC). The proposed converter directly transforms a fixed-amplitude, fixed-frequency AC supply into an AC output with adjustable amplitude and frequency at the load, utilizing four bi-directional switches. Sinusoidal Pulse Width Modulation (SPWM) signals are employed to control the switches, with modulation indexes and output frequencies regulated according to the V/f control method for efficient operation of the SPIM. The motor’s torque and speed responses are evaluated through simulations conducted in the MATLAB/Simulink program to verify the system’s performance.
