Abstract

This paper introduces a single-phase induction motor (SPIM) powered by a novel single-stage Boost DC-AC Converter, which replaces traditional inductors with coupled inductors to achieve higher voltage gain, reduced converter size, and improved overall efficiency. The proposed converter consists of three coupled inductors, two power diodes, and three semiconductor switches, enabling efficient conversion of DC input into high-gain AC output suitable for SPIM operation. One of the main advantages of this topology is its minimal component count, requiring only three switches, which helps lower costs, simplify control circuitry, and reduce switching losses. These benefits contribute to enhanced converter efficiency and improved performance in motor drive applications. To validate its effectiveness, MATLAB/SIMULINK simulations are conducted to evaluate the dynamic performance under both closed-loop control system and open-loop control system. Additionally, an experimental setup is built to test the converter’s real-world functionality under dynamic load conditions. The experimental findings align closely with the simulation results, confirming the feasibility and reliability of the proposed design. This converter presents a promising solution for efficient motor drives, particularly in applications that require compact, cost-effective, and high-performance power conversion systems.
