SINGLE PHASE TO THREE PHASE CONVERTER FOR VARIABLE SPEED DRIVE APPLICATIONS

This final report is mainly to give an overview about the “Single phase to Three phase converter for variable speed drive applications” project and also the progress of the project. Due to unavailability and high cost installation of three phase power network, power inverter is very important to address this problem. Here comes the purpose of the project to develop electronic converters that applicable for three phase equipment that equipped with variable speed drive (VSD) applications to operate in single phase supply. This project proposed two converter topologies for circuit modelling and simulation. There are PRC and PWM method. The modeling for the project will be done using PSPICE software. The model will be simulating based on the load requirement which is 3-phase motor for the converter design. Based on the simulation analysis it has been proved that these two methods can be implemented in order to achieve the project’s objective which to produce 3 phase power from single phase supply with improved performance and better efficiency. For this given time frame the project only focus on the methodology on how to develop the converter using proposed method but without control strategy. Further improvement or works can be carried out to improve the design by implemented control strategy for the converter.
