Abstract

In this project, effectiveness performances ofCOOLMOS and MOSFET switches in a single phase full bridge high frequency inverter circuit are investigated and compared in terms of output voltage and current waveform, switching losses and efficiency of the circuit catering for Uninterruptible Power Supply (UPS) system. Recently, semiconductor field came out with the latest technology of MOSFET family known as COOLMOS which is specified by the manufacturers to have lower switching losses with greater efficiency at lower cost. Therefore, the superior performances of COOLMOS over MOSFET in a single phase full bridge high frequency inverter design for UPS application are to be verified. The project is executed using simulation in the Cadence PSpice 14.2 software as well as by experimentation onthe Printed Circuit Board (PCB) layout. The layout of inverter circuit configuration is designed by using Multisim and transferred to the Ultiboard 2001 software. The simulation outcomes are confirmed to be as per theoretical study before comparing them with the experimentation results. From the simulation investigation of both switches, COOLMOS indicates better performances by having switching energy losses are reduced up to more than 50% compared to MOSFET and able to cater for high voltage application. Consequently from the experimentation the PCB layout, COOLMOS is validated to have superior performances compared to MOSFET in terms of experiencing lowerswitching energy losses.
