| Abstract |
The excellent switching capabilities of power MOSFETs permit the design of voltage fed inverters operating at high switching frequencies. By the use of FREDFETs the power circuit is very simple as no additional diodes and special snubbers are required. To ensure a safe operation of the inverter the switches have to be protected from overcurrent. In this paper a method is proposed to limit the drain current by modifying the gate driver characteristic. As a result a simple MOSFET driver is presented, which performs an overcurrent protection even under a short circuit condition. Its performance is proved by experimental measurements. |
