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.
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.
23rd March 2022, Amantys will be demonstrating the Power Semiconductor Data Acquisition and Logging System at PCIM 2022. Visit us at booth 256 in Hall 9, to discuss MMC technology, data logging and digital gate drives.
12th August 2021, A new version of the single on-module gate drive for nHPD2/LinPak and LV100/XHP2 is now sampling. This version has a configurable gate voltage making it suitable for SiC MOSFETs as well as IGBTs.
14th June 2021, Amantys releases the Power Semiconductor Data Acquisition and Logging System ("Data Logger"). If you are interested in making isolated on-state voltage measurements for converters using IGBTs and MOSFETs up to 3.3kV we would be delighted to talk to you.
1st July 2020, Dr. Angus Bryant presented "Simplifying the Calibration of On-State Voltage Drop for Online Junction Temperature Estimation in an Industrial Context" on Tue 7th July 2020 at 10:20 Stream 3 during PCIM Europe digital days.
