Full Wave Rectifier With Capacitor Filter Waveform. As the name implies this rectifier rectifies both the half cycles of the i p ac signal but the dc signal acquired at the o p still have some waves. To decrease these waves at the o p this filter is used.
But in full wave rectifier both positive and negative half cycles of the input ac current will charge the capacitor. In the full wave rectifier circuit using a capacitor filter the capacitor c is located across the rl load resistor. The main function of full wave rectifier is to convert an ac into dc.
In the previous article we have discussed a center tapped full wave rectifier which requires a center tapped transformer and the peak output of the rectifier is always half of the transformer secondary voltage.
In the full wave rectifier circuit using a capacitor filter the capacitor c is located across the rl load resistor. The output with filter of 1uf dampens the wave only to a certain extend because the energy storage capacity of 1uf is less. In the full wave rectifier circuit using a capacitor filter the capacitor c is located across the rl load resistor. The main duty of the capacitor filter is to short the ripples to the ground and blocks the pure dc dc components so that it flows through the alternate path and reaches output load resistor r l.
