DMAl2 main circuit principle circuit diagram

As shown in the figure is a simplified DMA 12 main circuit schematic diagram. It mainly consists of input circuit and electromagnetic interference (EMI) filter circuit, inrush current limiting circuit, input rectifier filter circuit, boost/power factor correction circuit and absorption loop, half-bridge power conversion circuit, output rectifier filter circuit, etc. Compared with DMA10, DMA12 adopts single-phase input, boost/power factor correction method and lossless absorption buffer circuit, while the half-bridge DC/DC power conversion and output rectification and filtering parts are the same as DMA10.
