Zener Diode Voltage Regulator Operation
The zener diode can be used as a type of voltage regulator for providing stable reference voltages. In this section, you will see how zeners can be used as voltage references, regulators,…
Zener Diode Breakdown Characteristics
The symbol for a zener diode is shown in Below Figure. Instead of a straight line representing the cathode, the zener diode has a bent line that reminds you of the…
Short Notes on Rectifiers & Filters
The device which operates at above 30V is called an electrical device and the device which operates with less than 30V is called electronic voltage. Even though the electronic devices…
How to Test a Diode using Multimeter
A multimeter can be used as a fast and simple way to check a diode out of the circuit. AÂ good diode will show an extremely high resistance (ideally an open)…
Diodes Voltage Quadrupler
The addition of still another diode-capacitor section to a Voltage trippler, as shown in Below Figure, produces an output four times the peak secondary voltage. C4 charges to 2Vp through D4…
Diodes Voltage Tripler
The addition of another diode-capacitor section to the half-wave voltage doubler creates a voltage tripler, as shown in Below Figure. The operation is as follows: On the positive half-cycle of the secondary…
Full Wave Voltage Doubler using Diodes
Voltage multipliers use clamping action to increase peak rectified voltages without the necessity of increasing the transformer’s voltage rating. Multiplication factors of two, three, and four are common. Voltage multipliers are used…
Half Wave Voltage Doubler using Diodes
Voltage multipliers use clamping action to increase peak rectified voltages without the necessity of increasing the transformer’s voltage rating. Multiplication factors of two, three, and four are common. Voltage multipliers are used…
Diode Clampers Principle
A clamper adds a dc level to an ac voltage. Clampers are sometimes known as dc restorers. Below Figure shows a diode clamper that inserts a positive dc level in…
Positive & Negative Diode Clippers
Diode Biased Limiters/Clippers First read basics of Diode Clippers. Click Here to read The level to which an ac voltage is limited can be adjusted by adding a bias voltage, VBIAS,…
