Uninterruptable Power Supplies (UPS) ensure continuity of supply by converting the DC voltage from a battery or battery bank to an AC voltage with the requested amplitude and frequency in case of power outages.

Depending on application requirements, a UPS can be built with a simple off-line configuration or with a double conversion online method for high-end, medium- or high-power UPSs as this also improves the quality of the power supplied to sensitive loads including computers, servers, equipment used industrial processes, instrumentation and telecommunication equipment.

We offer high-performance discrete devices including high- and low-voltage power MOSFETs, IGBTs, thyristors and silicon-carbide (SiC) diodes and power MOSFETs as well as galvanically-isolated and high-voltage gate drivers, power factor correction (PFC) controllers and high-performance STM32 microcontrollers to enable high-efficiency, high-reliability UPS designs.
