Electronic Aging Test Power Supply Manufacturer & Supplier serving the Osaka Market

In high-throughput electronic stress screening and life-cycle validation, reliability testing power systems operate under conditions distinct from standard laboratory power. When stress-testing power electronics, semiconductor devices (such as SiC MOSFETs and IGBT modules), and energy storage assemblies, the aging power supply must provide sustained, high-efficiency continuous power while resisting severe back-electromotive force (EMF), extreme dynamic step-loading, and continuous ambient thermal exposure.

A primary failure mode during extended burn-in testing across manufacturing lines is high-frequency ripple coupling into the Device Under Test (DUT), inducing localized thermal accumulation and skewing mean-time-between-failure (MTBF) calculations. Fenvix addresses this challenge through high-frequency interleaved soft-switching IGBT configurations coupled with multi-stage symmetric LC filtering. By operating switching frequencies well above the acoustic and typical control-loop bands, output ripple voltage is restricted to under 1% RMS, safeguarding sensitive internal dielectric boundaries within the DUT.

Furthermore, communication reliability during multi-channel stress cycles is ensured through isolated galvanically decoupled RS485 and fieldbus interfaces. By decoupling control electronics from primary high-current stages, Fenvix power supplies prevent common-mode ground loop interference, enabling precise automated parameter logging, ramp-soak profiles, and real-time fault detection without software interruption.
