AI Technical Summary
Traditional industrial frequency isolated UPS systems are bulky and inefficient, making it difficult to meet the high power density and high energy efficiency requirements of modern data centers, medical facilities, and high-end manufacturing.
The high-frequency isolated UPS uses a magnetically integrated bidirectional DC-DC converter circuit, including a bidirectional Buck-Boost circuit and a resonant isolation circuit. Through the interlaced magnetic integration structure of the magnetic components and the electrical isolation of the resonant isolation circuit, switching losses, copper losses, and iron losses are reduced, thereby improving power density and efficiency.
The UPS features a compact design, which reduces energy consumption, improves energy transmission efficiency and dynamic response speed, and meets the requirements of high power density and high energy efficiency.
