Voltage Multipliers are electric circuits to increase the voltage by a factor of two, three or four in case of Voltage Doubler, Tripler or Quarple respectively. The Voltage multiplier circuit uses capacitors and resistors to enhance the voltage level.
The Bridge type full wave rectifier can convert an AC to DC by the mean of four diodes in such configuration that the output peak voltage remains equal to secondary of transformer peak. In each half cycle, a set of two diodes conduct and block the current alternately.
A center tapped rectifier converts AC voltage to a DC voltage by the means of center tap transformer and two diodes. The output DC voltage of the rectifier is half of the secondary voltage.
Rectifiers are the circuit which converts AC Voltage to DC voltage. The half wave rectifier is the simplest type of rectifier with a single diode. The output of the rectifier is filtered with a capacitor filter to smoothen.
A diode can be connected in forward and reverse bias with a source. In Forward bias connection, a diode conducts current like a closed switch. Where in reverse bias, a diode blocks current like an open switch.
At the time of developing the PN junction diode, the depletion region is formed. Where free electrons and hole cross the conjunction between P- and N-region and recombine.
A semiconductor is a type of electrical material, which is used in electronic devices like PN junction diode, transistor and many more a replacement for a vacuum tube. The semiconductor can be intrinsic or extrinsic, where extrinsic has N-type and P-type.
Based on electrical resistivity, a material can be divided into three types: conductor, insulator, and semiconductor.
In RLC parallel circuit, resistor, inductor, and capacitors are connected in parallel across Alternating current source. In contrast to the RLC series circuit, the voltage across each component is the same and is taken as reference in the phasor diagram.
RLC Series circuit contains a resistor, capacitor, and inductor in series combination across an alternating current source. The behavior of components can be explained by phasor diagrams, impedance and voltage triangles.
