Bridge Rectifier With Capacitor Filter. Where v s is the peak of the input voltage source f is the frequency c is the capacitor and r the resistor. This smoothing capacitor is furthermore referred to as the reservoir capacitor mainly because it services similar to a reservoir tank and holds the energy in the course of the peak cycles of the rectified voltage.
V r v s 2 f c r. The filter normally used in the bridge rectifier is a capacitor filter. The filter made up of capacitor and resistor is known as capacitor filter.
This waveform shape is now much closer to a pure dc voltage waveform.
This type of low pass filter consists of two smoothing capacitors usually of the same value and a choke or inductance across them to introduce a high impedance path to the alternating ripple component. This type of low pass filter consists of two smoothing capacitors usually of the same value and a choke or inductance across them to introduce a high impedance path to the alternating ripple component. This substantial peak to peak voltage between the valleys along with the peak cycles are smoothed or reimbursed by means of filter capacitors or smoothing capacitors across the output of the bridge rectifier. Full wave rectifiers with capacitor filters are without question the workhorse and the unsung hero of the modern electronic world and for the gadgets we have come to enjoy.
