Rectifier over-current protection circuit diagram
As the voltage fluctuations or man-made distribution incidents often make the power grid generate surge over-voltage phenomenon, then the electronic equipments and power transformer rectifier circuit will be damaged. If varistor is connected to the input end of rectifier diodes and power transformer to play a protective role. The circuit is shown as the chart.
