HALF WAVE RECTIFIER WITH USING FILTER CIRCUIT

Basic Concept… What is Power supply? Need for Power supply Elements of Power supply Filters Voltage Regulators A basic Power supply

What is AC ? The voltage (and current) alternates between positive and negative over time and the resulting waveform shape is a sine wave. 

What is DC? A Direct Current (DC) supply stays at a fixed, regular, voltage all of the time, like the voltage from a battery.

Elements of a Power Supply Transformer Rectifier Filter Regulator

TRANSFORMER Transformer is used for to step up or to step down voltage.

Rectifiers Rectifier is a device which convert AC voltage in to pulsating DC.

Types of rectifier Depending up on the period of conduction Half wave rectifier Full wave rectifier Depending up on the connection procedure Bridge rectifier

Filter Circuits The output from the rectifier section is a pulsating DC. The filter circuit reduces the peak-to- peak pulses to a small ripple voltage. 11
