Würth Elektronik’s transformers have low interwinding capacitance

Additions to the WE-AGDT series of transformer series by Würth Elektronik provide interwinding capacitance lower than one picofarad, more topologies and higher output voltage options.

All transformers use the same compact SMT EP7 package with 11.3 x 10.95 x 11.94mm dimensions.

The WE-AGDT series is an auxiliary gate drive transformer series for up to 6W isolated auxiliary supplies targeting gate drivers systems for SiC MOSFETs and IGBTs. In these designs, the most crucial aspect is the transformer interwinding capacitance due to the high dV/dt, which is common in designs using wide bandgap devices, explained the company. The new models in this series feature interwinding capacitance is as low as 0.68pF and output voltages as high as 30V. Options now include LLC, half bridge or flyback topologies and one or two outputs which can be used in either unipolar or bipolar applications.

The WE-AGDT transformers comply with the IEC62368-1/IEC61558-2-16 safety standard and are AEC-Q200 qualified. They are suitable for use in industrial drives, AC motor inverters, HEV/EV charging stations, solar inverters, uninterruptible power supply devices and active power factor correction.

Like all products in the Electronic Components 2022/2023 catalogue, WE-AGDT samples are available ex-stock without minimum order quantities (MOQ). Free samples are also provided.
Reference designs are available together with PCB fabrication and layout design files.
