Abstract

In this paper, comparative study of MOSFET and COOLMOS in a high frequency inverter design is investigated. Recently, semiconductor power switch need greater efficiency with low switching energy losses. The study is performed using a single phase full bridge inverter design with a high frequency of 500 kHz, 150V input voltage, 0.5 duty ratio with an isolation at the load in providing a stable AC output catering for Uninterruptible Power Supply (UPS) system. MOSFET is widely use; COOLMOS is a new technology of MOSFET family using a new device concept called super-junction. Thus, will COOLMOS replace the traditional device MOSFET in high frequency inverterdesign for UPS application is to investigate. This project is carried out via simulations using Pspice Cadence PSD 14.2 software and via experimentation on Printed Circuit Board (PCB) layout. PCB layouts are designed using Multisim and Ultiboard 2001 software. Simulation and experimentation investigation shows COOLMOS having a superior performance with switching energy losses are reduced up to more than 50% compared to MOSFET. Verifying COOLMOS can replace the traditional device MOSFET in high frequency inverter design for UPS application to meet the need greater efficiency power switches with low switching energy losses.
