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.
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.
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.
Power Factor (PF) play an important role in average power dissipation in an ac circuit. PF leads to the concept of three different real, reactive and apparent power, which is better explained by Power triangle.
