The AVL Ripple Generator™ was designed to add mid-frequency AC currents with up to 250 kHz to an existing DC bus. Additionally, the AVL E-STORAGE BTE™ DC supply features an internal ripple emulator to cover the low-frequency range. Together they provide an outstanding solution to emulate the inverter behavior at the test item and may also be used as a powerful broadband signal source for impedance measurements.
- Ripple generation from 300 Hz to 250 kHz
- Amplitude up to 200 App
- AVL-patended coupling network and current control
- Easy integration to AVL automation systems AVL PUMA 2TM, AVL LYNX 2TM
- Easy installation in existing testing equipment and tested compatibility with AVL E-STORAGE DC supplies and AVL Cell TesterTM
