| Abstract: | Rectifier filter circuit is widely used in the DC equipment.Among the circuit,the selection of the filter capacitor is important to the quality of ripple voltage and the output DC voltage.According to the principle of the rectifier filter circuit,the process of ripple voltage is illustrated,and the design and calculation approach of capacitor is given,then the capacitance selected calculation model of capacitance selection is built up,finally the relationship curve between the ripple voltage,resistor and filter capacitor is depicted.The experiment verifies that this method is scientific and suitable for the design and selection of filter capacitor. |
