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.
