Gate drive transformers are used to deliver the controlling gate-voltage pulses between the drain and source of a MOSFET, while providing isolation between the MOSFET and the controlling drive circuit. Gate-driver circuits need an isolated (floating) bias supply to maintain the required turn-on bia...

Auxiliary Gate Drive Transformer The WE-AGDT series from Würth Elektronik allows implementing discrete SiC gate driver designs easier than ever before. These standard parts are compact SMT transformers optimized for silicon carbide applications. With extremely low interwinding capacitance, the WE-AGDT ...

The design includes the LM5180-Q1 flyback converter, which works with an input voltage range from 4.5 V to 70 V. It controls the output voltage by measuring it from the primary side, so it doesn’t need extra parts like an opto-coupler or a third winding on the transformer. It also ...
This paper presents the analysis, design and hardware implementation of a medium voltage gate-driver for a 3 kV IGBT application. The immediate application of such device is a 10kW Electronic Transformer (Solid State Transformer) prototype, applied to a single phase 7967/220V distribution line. In...
