Power Supplies
Power SuppliesRectifiersBasic DC Power SupplyA circuit that converts AC line voltage to DC voltage and supplies constant power to circuit or system.Block Diagram
Basic DC Power SupplyRectifiersHalf-Wave RectifierCenter-Tapped Full-Wave RectifierBridge-Type Full-Wave Rectifier
Half-Wave RectifierA circuit that converts an AC sinusoidal input voltage into a pulsating DC voltage with one output pulse occurring for each input cycle
Half-Wave RectifierPeak Inverse VoltageHalf-Wave RectifierTransformer CouplingAdvantages of Transformer Coupling:Source voltage could be stepped down as neededThe AC source is electrically isolated from the rectifier, thus preventing the shock hazard in the circuit.
Turns Ratio
Half-Wave RectifierFull-Wave RectifierAllows unidirectional (one-way) current through the load during the whole 360o of the input cycle.
