Enhanced modules aid EV powertrain tests

Semiconductor test equipment supplier Advantest has introduced two modules that enable its T2000 IPS system to test high-voltage and high-power devices used in the power trains of electric vehicles (EV/HV). The enhanced MMXHE (multifunction mixed high voltage) and MFHPE (multifunction floating high power) modules enable massively parallel, high-performance testing by leveraging Advantest’s multifunctional pin design, which allows flexibility in assigning test resources to any pin.

“As electric vehicles evolve, it is increasingly important to provide test solutions that support higher voltages to ensure the reliability of power-train parts,” said Satoru Nagumo, executive vice president of Advantest’s ADS Business Group. “Our new modules for the T2000 IPS system were developed to meet the testing needs of advanced analog devices for the rapidly growing automotive electronics market.”

The MMXHE and MFHPE modules optimise testing efficiency and lower the cost of test by providing 64 output channels and 36 output channels respectively.

Each pin has multiple measurement capabilities, which minimises the number of relays on the loadboard for streamlined operation and a simpler loadboard design.

The modules can measure voltages up to 300V with accuracy up to the order of 100µV, as required in testing ICs in power trains, controls and sensors of EV/HVs.

Module resources can be stacked or ganged, giving customers the ability to adjust the tester’s functionality and throughput to achieve their desired performance.

This versatility helps to ensure the long-term usability of the T2000 IPS tester.

The system’s capabilities include highly accurate testing of parametric measurement units (PMU), high-voltage digital functions, differential voltages, time measurements, Iddq, and arbitrary waveform generator/digitiser functions.

With the T2000 IPS, each of these tests is assigned to a single pin, resulting in faster processing and higher throughput.

Advantest will showcase the new T2000 IPS modules in its exhibit at the SEMICON Japan trade show (13-15 December) in Tokyo.
