Datasheet

The Ripple Generator from IMP is a high performance solution designed for demanding testing of electric vehicle high voltage bus systems. It is developed to meet key industry standards, including LV123, MBN 11123, VW80300, and ISO 21498-2:2021.

Engineered for advanced ripple voltage and current immunity testing, the system supports requirements such as ISO 21498-2 section 6.6 for immunity to voltage ripple, as well as VW 80300 specifications like EHV-09 for applied high voltage ripple and EHV-13 for high voltage lifetime testing. It also aligns with equivalent OEM specific test standards.

This scalable and high performance solution is ideal for testing high voltage batteries, inverters, and hardware in the loop systems. It is built to handle the most demanding validation scenarios, delivering reliable and precise results for modern electric vehicle development.

Power:

Up to 756kVA+

Voltage:

350Vac L-N/606Vac
L-L or Ā±500Vdc

Frequency:

Up to 1,200Hz

Key features:

System components:

  • Ripple Generator (Switchmode Power Amplifier + Coupling Network)
  • Shield BoxĀ (for ripple current injection; expandable in conjunction with the IMP RiHV to a standard-compliant LISN / “artificial network”, with which standard-compliant measurements of interference emissions (ISO21498-2 6.3 “Generated voltage slope” and 6.5 “Generated voltage ripple”, VW80300 EHV-05 “Generated HV voltage dynamics”, EHV-07 “HV voltage dynamics of energy storage devices” and EHV-08 “Generated HV voltage ripple”) can also be carried out)

Ripple System Controller

  • Automatic control of the ripple voltage or ripple current at the DUT
  • Parallel operation of up to 6 ripple generators (up to 720 App / 1200 App possible)

High-performance ripple outputs:

  • Ripple current: 120 App / 200 App (adjustable, single device)
  • Ripple power: up to 4 kV Arms (single unit)
  • Ripple voltage: 350 Vpp (@ 120 A) / 170 Vpp (@ 200 A)

Scalability:

  • Parallel operation is possible almost without limit ā€“ common setups: 3 x 200 app systems
  • Wide frequency range:Ā 300Hz (150 Hz) – 250 kHzĀ , without range switching
  • Non-invasive ripple injection:Ā DC voltages from 0 to 1200 V areĀ supportedĀ as standard.
  • Compact design:
    • Ripple Generator (<120 kg at 600 App)
    • Shield Box (<60 kg at 1200 V / 1200 A)
  • Energy efficient:Ā Only one 230 V / 16 A 1~ socket required for >600 app systems.
  • Robustness:Ā Protected against DUT failures under full load
  • Easy integration:Ā RS485 or LAN interfaces, ASCII-based protocol for test bench automation
  • Field-proven performance:Ā Ideal for high-power applications such asĀ e-axleĀ and inverter tests or power HIL test benches,Ā but also for all other high-voltage on-board components (air conditioning compressors, hydraulic pumps, on-board chargers, on-board power converters, etc.)

High-performance ripple outputs:

  • High-voltage battery tests
  • Inverter andĀ e-axleĀ tests
  • Power hardware-in-the-loop (HIL) testing
  • generally all high-voltage electrical system components

Advantages ā€“ proven by many installations already carried out:

  • Highest performance and reliability in the industry
  • Compact and portable design
  • Tailor-made solutions for individual customer requirements
