Complete Power Electronics Test System
Power Electronics Automated Test Solutions
Integrated automated test systems for AC/DC converters, DC/DC converters, power modules and other power electronics, covering input/output performance, dynamic load, protection, high-voltage isolation, burn-in and production data.
Why Automated Power Test
Power electronics testing often involves input conditions, output load, voltage, current, power, waveform, protection, dynamic behavior, isolation and burn-in.Sequence Automation

Power Test Architecture
This is a typical architecture and does not imply that every project includes every resource.Input & Line Condition Test
Covers input voltage variation, line regulation, voltage sag and over/under-voltage behavior.
Output Performance Test
Covers output voltage, output current, load regulation, ripple and Periodic and Random Deviation (PARD).
Dynamic & Transient Load Test
Uses electronic load or controllable load conditions to verify DUT response during load changes.
Protection & Fault Condition Verification
Executes overload, short-circuit and over/under-voltage tests under controlled conditions.
High-Voltage & Isolation Test
For products requiring electrical isolation verification, Hi-Pot / HV resources can be integrated into the production test flow.
Burn-In Integration
Power source, multiple DUT, load/monitoring, temperature/status, test software and data logging form a typical burn-in integration concept.
Electrical & Power Measurement
DMM, oscilloscope, power meter and electronic load can be combined for voltage, current, waveform, power, ripple and harmonics test.
Universal Power Test Platform
The universal platform concept emphasizes common test architecture, configurable test sequence, interchangeable/model-specific fixture concept, shared instrument resources and model configuration.
Typical Project Instrumentation
Chroma Electronic Load, AC/DC Source, Sorensen DC Source, Agilent DMM, switch matrix, Tektronix MSO and Yokogawa WT230 Power Meter are historical project configuration examples only.
Custom Test Hardware
Customized PCB, customized relay cards, communication PCB and custom test modular instruments can support interface, switching, signal conditioning and fixture electronics.
