Series DC Voltage Regulator: The output voltage of a d.c. source, whether it is a rectifier or any other machine, changes with the load current as well as with the input voltage variations. In order…

Electrostatic Generators: Van de Graaff generators are essentially high voltage but low power devices, and their power rating seldom exceeds few tens of kilowatts. As such Electrostatic Generators machine which effectively convert mechanical energy into…

Van De Graaff Generator Working Principle: The schematic diagram of a Van De Graaff Generator Working Principle is shown in Fig. 6.6. The generator is usually enclosed in an earthed metallic cylindrical vessel and is…

Deltatron Circuit or Cascaded Modular Voltage Multipliers: A combination of Cockcroft-Walton type voltage multiplier with cascaded transformer d.c. rectifier is developed recently for very high voltages but limited output currents having higltstability, small ripple factor and…

Voltage Drop on Load and Regulation: The change of average Voltage Drop on Load from the no load theoretical value expressed as a percentage of no load voltage is called the Regulation. The change in…

Voltage Multiplier Circuits: Cascaded Voltage Multiplier Circuits for higher voltages are cumbersome and require too many supply and isolating transformers. It is possible to generate very high d.c. voltages from single supply transformers by extending…

Voltage Doubler Circuits: Both full wave and half wave rectifier circuits produce a d.c. voltage less than the a.c. maximum voltage. When higher d.c voltages are needed, a Voltage Doubler Circuits or cascaded rectifier doubler…

Half and Full Wave Rectifier Circuits: Half and Full Wave Rectifier Circuits for producing high d.c. voltages from a.c. sources may be (a) Half wave, (b) Full wave, or (c) Voltage doubler type rectifiers. The rectifier…
