1. Summary

TF1000D is a portable double pulse tester that integrates complete core components such as high voltage power supply, power inductor, double pulse signal generator, UI control interface, etc.

u TF1000D is designed with a portable connector for current/voltage probe. It can easily and accurately read the test waveform of the power half bridge topology structure and transmit to the oscilloscope of the user. Engineers no longer need to configure additional peripheral instruments and meters.

u TF1000D is designed to help engineers to measure the dynamic performance of TO-247-3L/TO-247-4L packaged SiC MOSFET . Its main circuit includes the main circuit loop and the driving circuit. Due to the overall low stray inductance circuit design, when the MOSFET quickly turns on and off and reaches 500V/15ns (dv/dt up to 33KV/us), the waveform oscillation at both ends of the device can still be controlled at an extremely low level, making it easy to accurately measure and calculate the dynamic parameters of the tested SiC MOSFET device.

u The upper PCB zone of TF1000D is integrated with the connectors for different types of current/voltage probe. Connectors are all designed and laid out according to the requirements of precise measurement in order to fully utilize the performance of the probes. For high voltage differential probe, we installed customized 4mm banana socket which can achieve low distortion measurement and acquisition of 500MHz high-speed voltage signals while reducing waveform oscillation. For high frequency current acquisition: Two of our company's latest bolt type coaxial current shunt have been set up to detect the high-speed current waveforms of the upper and lower MOSFET, respectively. These shunts can be installed or removed easily with bare hand, or replaced with shunts of different resistance value.

This equipment is able to switch the hardware circuit connections of different test project (DUT device switch characteristics/reverse recovery characteristics) in the double pulse experiment through the visual UI software control interface in front. When setting up the software, the drivers of the upper/lower bridge arms, internal relays, and the connection positions of the air core inductors will be synchronously configured. Engineers can quickly and accurately switch settings and avoid incorrect settings.

The dimensions of TF1000D is just 214*193*123mm, which is easy to carry and DEMO.
