New Dual-Output Gate Driver Evaluation Board from SemiSouth for Microsemi and other power modules
SemiSouth Laboratories, Inc. has announced the SGDR2500P2, a dual-output, two-stage, opto-isolated gate driver board intended for use with power electronics modules that incorporate SemiSouth’s vertical-trench junction field-effect transistors (VJFETs) as the primary switches. The board provides electrically isolated high-side and low-side outputs with peak current levels of +20/-10 A, enabling fast switching speeds and yielding record-low switching energy losses.
The The SGDR2500P2 self-generates isolated ±15 V supply voltages, eliminating the need for multiple power supplies. The board’s maximum switching frequency is 100 kHz, enabling the user to leverage the high-frequency capability of SiC technology and reduce bulky, costly magnetic components. Moreover, the duty cycle can be adjusted from 0% to 100%, increasing versatility and making the board suitable for a variety of applications.
Explains SemiSouth’s Director of Sales, Dieter Liesabeths: “The isolated high- and low-side outputs make it easy to drive half-bridge power modules without requiring additional isolation transformers, resulting in tremendous savings in space, weight, and cost. Also, the built-in two-stage driver minimizes switching and conduction losses.”
Applications include hard-switched bridge topologies, inverters, and converters, as well as product evaluation.
