Electrolytic Capacitor Failure and How it Affects Circuits
For example, a failing capacitor can affect the DC output level of a DC power supply because it can''t effectively filter the pulsating rectified voltage as intended. This results in a lower average DC voltage and causes a corresponding erratic behavior due to unwanted ripple – as opposed to the expected clean DC voltage at the load.
Capacitor Filter Operation
Capacitor filter. Fig. shows a typical capacitor filter circuit. It consists of a capacitor C placed across the rectifier output in parallel with load RL. The pulsating direct voltage of the rectifier is applied across the capacitor. As the rectifier voltage increases, it charges the capacitor and also supplies current to the load. At the end of quarter cycle …
