UPS (Uninterruptible Power System), also known as Uninterruptible Power Supply, is a constant voltage and frequency uninterruptible power supply that contains energy storage devices and is mainly composed of inverters. Mainly used to provide uninterrupted power supply to a single computer, computer network system, or other power electronic devices. When the mains power input is normal, the UPS stabilizes the mains power and supplies it to the load for use. At this time, the UPS is an AC mains power stabilizer, and it also charges the internal battery; When the mains power is interrupted (due to an accident power outage), UPS immediately supplies 220V/380V AC power to the load by inverting the power from the internal battery, ensuring that the load maintains normal operation and protects the load's software and hardware from damage. UPS equipment usually provides protection against both high and low voltage.

Hongmei utilizes Trench Field Stop IGBT technology and adopts high-density device structure design and advanced ultra-thin chip processing technology to launch a new generation of Trench FS IGBT series products. This series of products significantly reduces device saturation voltage drop and turn off loss by optimizing carrier injection efficiency and carrier distribution, thereby reducing device power consumption and improving system efficiency.
