Positive Regulator Circuit with PNP and NPN Transistor Boost

Positive regulator Circuit with PNP and NPN Transistor Boost

Here the schematic diagram of positive regulator with PNP and NPN transistor boost. Inside the circuit, Q1 and Q2 are wired in the classic SCR or thyristor configuration. In which higher input voltages or minimum element count are needed, the circuit for thyristor boost could be applied. The thyristor is working in a linear mode with its cathode as the control terminal and its gate to be the output terminal. This is known to be the remote base configuration.

About Power Supply
A power supply is a device that supplies electrical energy to one or more electric loads. The term of "power supply" is most commonly applied to devices that convert one form of electrical energy to another, though it may also refer to devices that convert another form of energy (e.g., mechanical, chemical, solar) to electrical energy.
A power supply may be implemented as a discrete, stand-alone device or as an integral device that is hardwired to its load. In the latter case, for example, low voltage DC power supplies are commonly integrated with their loads in devices such as computers and household electronics. More explanation about power supply can be found at wikipedia.org

This is the tutorial about "How to build an AC to DC power supply ". The video tutorial covers the basics of diodes, bridge rectifiers, and how to build simple unregulated AC to DC power supplies than can handle a few mA up to several Amps.
