AE Techron HVR 1000: High-voltage ripple test system for E-mobility and aerospace

A Solution for Demanding Test Scenarios

With the increasing deployment of electric vehicles (EVs) and electrified aircraft systems, the demand for accurate high-voltage component testing is growing. One of the critical parameters is ripple – rapid and repetitive voltage fluctuations superimposed on the DC signal. These disturbances can negatively impact reliability, electromagnetic compatibility (EMC), and safety. AE Techron addresses these challenges with the advanced HVR 1000 high-voltage test system.

What Is the HVR 1000?

The AE Techron HVR 1000 is a complete high-voltage ripple test system designed to assess component immunity from ripple voltages in the 10 Hz to 200 kHz range, with output up to 50 Vp and 200 Ap. With up to 1000 VDC and 60 kW of output power, the system supports a wide range of automotive and aerospace test applications.

Key Features and Advantages

1. High Flexibility and Precision

The HVR 1000 supports sinusoidal, trapezoidal, square, and custom waveform generation with precise control of frequency and amplitude. It accurately replicates standardized and real-world ripple waveforms, including harmonics—essential for meeting standards such as Stellantis C_ET_03_HV_V and VW EHV-08.

2. Industry Standards Compliance

The system meets or supports a wide range of international test standards, including:

• ISO 21498-2
• MBN LV123
• VW 80300 and VW 80303
• MAN CVS 43:2021-01
• Stellantis CS.00245

3. Device Safety and Protection

Equipped with multi-layer protection against overvoltage, overcurrent, and overheating, the HVR 1000 can automatically shut down in case of failure to protect the device under test. Fast fault shutdown and precise voltage clamping ensure safe testing of sensitive components such as BMS and traction inverters.

4. Future-Ready Design

Besides the main model, AE Techron offers the HVR 1000RG, a ripple generator-only version for labs that already have DC supplies. Both systems use the 3110A software with a test standards library containing over 3,600 predefined tests.

Conclusion

The HVR 1000 offers a modern, powerful, and safe solution for high-voltage ripple testing in electric mobility and aerospace. With its flexibility, standards-based profiles, and advanced waveform capabilities, it is an ideal choice for both development and compliance testing.
