Rectification
Full-wave
A process of converting a.c. to d.c. by a rectifier.
Reverse bias
Forward bias
Conduct current
does not conduct current
Low resistance
high resistance
type of rectifier
thermionic diode valve
selenium rectifier
semiconductor rectifier
supply larger amount currents
can withstand higher potential differences
sizes are smaller than metal rectifiers
Half-wave
first half-cycle
potential difference across resistor i created with the same value as applied potential difference
in forward direction of the rectifier
second-half cycle
current is in reverse biases direction
As the resistance in rectifier is very hgh
no current flow
potential difference across resistor is zero
Types of circuits to produce full-wave rectification
Center-tap full-wave rectification circuit
bridge full-wave rectification circuit
produced when a rectifier is connected in series with an a.c. input and d.c. load such as resistor
