Intelligent DC- and AC Power-Cycling Platform for Power Electronic Components

Abstract

In this paper, a state-of-the-art, intelligent power cycling platform is introduced in detail. The test platform allows to perform both DC-and AC-power-cycling tests on power electronic discrete components as well as modules up to 70 ARMS / 700 VDC . Vital parameters of the device under test (DUT) as junction temperature and on-state voltage are measured during the test. A 19" -standard industrial rack is used, which enables a flexible and compact test platform design. Test results for power cycling are presented for validation purposes.

Measuring Temperature Swing with Optical Fibers during Power Cycling of Power Components

“…Large space around the DUT converter is saved for optical fiber holder placement. More details of the setup can be found in [16].…”

Multi-timescale Modelling for Reliability Analysis of Power Electronic-Based Systems

“…As for conventional damage modelling approaches, this modelling approach requires empirical fitting based on experimental results. The modelling is primarily characterised using number of cycles to failure and the stressors of the chosen damage model, just as conventional damage modelling [70,71,72,58,73,74]. Only one additional parameter is needed for characterisation, namely the evolution of the degrading parameter that is to be modelled [75].…”
