Simulation of a low cost single phase to three phase converter using arduino

Abstract

This paper proposes a single phase to three phase conversion system composed of a rectifier, capacitive filter, Arduino controller, resistive switching network, buffer circuit and amplifier circuit. The proposed topology permits to operate at different frequencies by changing the coding of Arduino pulse generator. Although the effectiveness of previous work is acknowledged, none have assessed the multilevel wave generation using arduino and resistive switching network. It reduces the cost by using resistive switching technique and better accuracy as the input pulse is divided into 20 steps and finally a stepped sine wave is obtained. This converter can be easily used for motors up-to 5HP. Analysis and simulated results are presented to validate these features.
