While independent research and development, the company strengthened cooperation with enterprises, universities and research institutes, vigorously develop key technologies with independent intellectual property rights, form independent core technologies and proprietary technologies, and accelerate the pace of industrialization of scientific and technological achievements. The company and well -known universities such as Xi'an University of Electronic Science and Technology established the relationship between industry -university, research, research and research, and mastered a number of core technologies with independent intellectual property rights, effectively ensuring the smooth development of the company's research and development activities, and providing technical reserves for the leading strategy of semi -guided series product technology technology. And support.

1. 1.5kW PFC+LLC (Resonant Half Bridge
Due to the small power, the single -tube PFC+half -bridge can meet the application, and the circuit is simple and the components are small. MOS generally uses 20-50A, 600V, 650V MOS.

2. 3.3KW Bridgeless PFC+Resonant full bridge
Bridge PFC requires 2PCS MOS and 2PCS rectification pipes without entering the rectifier bridge, because there are some losses that are not input. But EMI is more difficult to deal with. The resonant bridge requires 4PCS MOS, which is complicated to drive circuits and is suitable for large power occasions.

3. 6 ~ 15kW Vienna three -phase PFC+three levels of resonance full bridge
The circuit is very complicated and requires a special driver to control the circuit. The advantage is that MOS can use 600,650V for easy purchase. Due to the use of multiple MOS, the calories are divided, the heat dissipation will be better dealt with.
