Ripple Generator
for testing in accordance with LV123 / MBN 11123 / VW80300 / ISO 21498-2:2021
Ripple Generator
Switchmode Power Amplifier + Coupling Network
- Very high Ripple Output Current: 120 App / 200 App (selectable; single unit)
Very high Ripple Output Power: 4 kVArms (single unit). - Very high Ripple Output Voltage: 350 Vpp (@ 120 A setting) / 170 Vpp (@ 200 A setting)
- By far most energy efficient available: only single 230 V 16 A 1~ outlet required for > 600App system
- By far most lightweight, small and portable system: Ripple Generator 600 App: < 120 kg
- Frequency range: 150 Hz -250 kHz; no range switching required
- Non-invasive parallel ripple injection
- Supported DC voltages: 0 to 1200 V
- Interface / Connectivity: RS485 or LAN, simple ASCII based protocol (AK), easy
integration into any test stand automation system
- Rugged: Protected against all kinds of DUT failure (even under under full DUT load)
- Field proven performance in the most demanding applications (high power axle- / inverter and Power-HIL test stands, not only simple HV vehicle battery testing)
Customer references available on request - Shield Box max. DC current: 1200 A
Ripple System Controller
- automatic (narrowband, closed-loop) DUT ripple voltage or DUT ripple current control
- parallel operation of up to 6 Ripple Generators (up to 720 App / 1200 App)
- Scalability: Virtually unlimited parallel operation of Ripple Generators in
customized setups; currently most popular typical customer setups are 3 x 200 App systems
