Amantys Power Electronics is combining the world of power electronics with advanced digital and software technology to improve the availability, cost and efficiency of high power systems.

Data Logger

 

Amantys launches the Power Semiconductor Data Acquisition and Logging System. This sophisticated measurement system allows customers to capture detailed measurements of device operation in the inverter stack, and track IGBT, SiC MOSFET and diode forward voltage drop during converter operation. It is designed to be fitted to a single phase leg (half-bridge) in an existing inverter stack, and works with any gate drive. Using the captured data, customers can calculate junction temperatures and correlate them with their their own measurements or online temperature models. Automatic device calibration and estimation of Tj remains a research topic and is not possible with the first release of the Data Logger.

Next Generation IGBT Module Support

A new version of our dual channel Gate Drive suitable for single IGBT and SiC modules in the nHPD2/LinPak and XHP2/LV100 packages is now sampling. This compliments the original version which was suitable for use with nHPD2 and LinPak only. Supporting 3300V and 1700V IGBTs and SiC MOSFETs, the gate drive is designed to mount directly on top of module allowing them to be mounted side-by-side and still meet creepage and clearance rules. Designed to railway traction standards the new version will be in production in early 2022.

The new version (shown below) has an improved power supply allowing configurable gate voltage suitable for SiC MOSFETs.
