High-Frequency Switching Rectifier Module

GF22020-9

The GF22020-9 high-frequency rectifier module utilizes full-bridge LLC resonant soft-switching technology for high efficiency and incorporates passive PFC technology to ensure a high power factor. It employs a hybrid cooling system that combines natural convection with forced air cooling; the module operates via natural cooling under light loads, aligning perfectly with the actual operational requirements of power systems. Furthermore, the cooling fan features a combined temperature and current control mode, resulting in low noise and an extended fan service life.
