As the voltage and current reverse, 60 times a second, the level goes from around 170 volts peak down to zero volts and on down to -170 volts and then it repeats. The capacitors filter this drop by supplying the appropriate voltage to keep the circuit smooth. As the voltage rises back up again, it recharges the capacitor.
Two effects of output capacitors are critical here: the effect on the output voltage ripple and the effect on the output voltage after load transients. First, a general remark should be made about ...
Capacitors. Capacitors are electrical components that store electrical energy in an electric field. They are used to provide filtering, smoothing, and timing functions in electronic circuits. Capacitors are commonly used in circuits to stabilize voltage or to filter out noise in a signal. Capacitors come in different types, including ceramic, electrolytic, and tantalum. Each type …
