Will the input voltage increase after the filter capacitor is damaged? |Focus on mid-to-high-end brand capacitor manufacturers

by:Shenmao     2021-05-22
The damage of the filter capacitor of the switching power supply will not cause the input voltage to rise. The voltage at the input of the electronic circuit is usually fixed. Even if the filter capacitor is damaged, it can be filtered by the rectifier diode and the secondary filter capacitor. Generally, the withstand voltage specification of the filter capacitor is 1.7 times the output voltage. The allowable temperature is 105 degrees, and the commonly used filter capacitor capacity is generally 2200 MF. At present, we are trying our best to improve the voltage management accuracy of the switching tube, so as to achieve higher power efficiency with less cost. The damage of the filter capacitor in the switching power supply will not affect the peak value of the filter capacitor at the output end, because the switching power supply will constantly check the voltage at the output end. Once an error is found, the output of the switching tube will be adjusted. In this case, small temperature changes will be automatically compensated.
