In a power supply, a capacitor is used to filter the pulsating DC o/p once rectification so that an almost stable DC voltage can be supplied to the load. 3). What are the limitations of the capacitor filter?
A capacitor is used to filter out the DC signal. This can be done by connecting the capacitor in series in the circuit. The following circuit is the capacitive high-pass filter. In this, signals like DC or low frequency will be blocked.
In the next paragraphs we are going to endeavor to determine the formula for computing filter capacitor in power supply circuits for guaranteeing smallest ripple at the output (determined by the attached load current spec). C = I / (2 x f x Vpp) where I = load current f = input frequency of AC
DC filters circuits are mainly used with the rectifier outputs to obtain a stable, smooth DC voltage from a pulsating DC input. Referring to the output waveform of a full wave rectifier we can find that the output DC is consists of two positive half cycles.
It is used for RFI removal (radio frequency interference) for power or signal lines to come in or exit equipment. This capacitor can be connected after the voltage regulator to get a smooth DC power supply. 1). What is the function of a filter capacitor?
The circuit diagram of the filter capacitor is shown below. In this circuit, the capacitor works like a high pass filter that allows high frequencies and blocks direct current. Similarly, they can also work as a low pass filte r to allow DC and block AC. Here the capacitor is connected in parallel with the component instead of connecting in series.
