FAQ
A high‑current ripple generator system is a specialized test system designed to superimpose controlled AC ripple current onto a DC current or DC operating point, enabling realistic simulation of ripple conditions seen in real‑world power electronics and battery systems.
1200 A_pp (peaktopeak) refers to the maximum amplitude of the AC ripple current that can be injected. This allows testing of components and systems under very high ripple stress conditions.
The main purpose is to:
Simulate realistic ripple currents
Stress components thermally and electrically
Validate durability, lifetime, and robustness
Test systems under operating conditions that cannot be reproduced with DC sources alone
DC power supply → Provides steady DC voltage or current
Ripple generator → Injects controlled AC current ripple on top of an existing DC operating point
Ripple generators are used when dynamic current stress is the key test requirement.
Common applications include:
Battery and battery pack testing
EV powertrain and DClink validation
Capacitor and busbar testing
Power electronics and inverter validation
Automotive and industrial endurance testing
It is also used for demanding e-vehicle HV bus tests according to LV123, MBN 11123, VW80300 & ISO 21498-2:2021
