In power electronics applications, electrolytic capacitors are subjected to demanding ripple current conditions, which directly affect their service life and reliability. The Chroma 11800 is a specialized load and life test system designed to simulate these conditions and evaluate the real performance of components.
This system applies AC (ripple) current and DC bias simultaneously, reproducing typical operating scenarios in switch-mode power supplies, inverters, and industrial systems.
Instrument functionality
The tester integrates two main sources:
- Ripple current source (AC): simulates the alternating current flowing through the capacitor
- DC bias source: reproduces the nominal operating voltage
It also monitors critical parameters such as RMS current, peak voltage, and the dynamic behavior of the component under test.
Key capabilities
- Ripple current up to 30 A
- Selectable frequencies: 100 Hz, 120 Hz, 400 Hz, and 1 kHz
- DC bias up to 500 V
- Accurate measurement of electrical parameters
- Programmable timer for long-duration tests (up to 10,000 hours)
- Built-in protections (overcurrent, overtemperature, overload)
These features make it a key tool for stress testing and accelerated aging.
