Fast Switching 1200V Normally-Off SiC VJFET Power Modules

An all SiC based power module for use in high frequency and high efficiency applications has been developed. Using parallel combinations of 1200V enhancement mode SiC VJFETs and Schottky diodes, a total on-resistance of only 10m was achieved at 100A drain current in a commercially available standard module configured as a half-bridge circuit. Careful attention to module layout, gate driver desi...

Device/Circuit/Architectural Techniques for Ultra-low Power FPGA Design

Field Programmable Gate Arrays (FPGAs) are widely used for implementation of dig ital system design due to their flexibility, low time-to-market, growing density and speed. But the Power consumption, especially leakage and dynamic power has become a major concern for semiconductor industries. FPGAs are less power-efficient than custom ASICs, due to the overhead required to provide programmabili...

An Innovative Simple Test Circuit for Single-Phase Short Circuit Making Test of High-Voltage Switching Devices

Nowadays, high-voltage circuit breakers have reached such high short-circuit capabilities that testing them under the full rated voltage is generally not possible with direct tests, and they are conducted by using the synthetic test methods. Although the phenomena associated with making tests is of particular importance especially in case of load break switches, but making tests are rather d...
