the protection circuit of power circuit
The current in power circuit is great and wecan adopts fuse,diode,transistor circuit to limit the current.Fuse is the simplest protection component.Picture a,b are the examples of setup method of fuse.The fuse is connected with the protection circuit and loads in series.Classify by fusing time,there are fast type,low type and normal type.We should select appropriate fuse based on the different loads and driving circuit.
