Electronic Power Controller Circuit






Electronic Power Controller Circuit diagram


This is an electric power controller which implemented the bidirectional triode thyristor(TRIAC). This circuit can manage the electrical power using the a single variable resistor.

This circuit is applied for the dimmer which adjusts the light from the bulb. This circuit adjusts the quantity of the electrical current which flows via the load together with the bidirectional triode thyristor and controls the electric power. It truly is only the alternating voltage that may be controlled with this circuit and it is impossible to perform the control in the DC voltage.

Simply because it controls the passing time in the alternating current by the bidirectional triode thyristor, the electrical current which flows via the load is not the clean sine wave type. Due to the fact it's, there is limitation in the equipment which may be controlled with this circuit. The bidirectional triode thyristor is usually called by the trade name TRIAC.

The equipment which can be controlled
  • The equipment which works by the resistance. Such as the the tungsten-filament lamp, the soldering iron and so on.
  • The equipment which is using the AC series motor(with the brush). Such as the drill, the electric fan, the cleaner and so on.

The equipment which can not do the control
  • The fluorescence light.
  • The synchronous motor(using the capacitor)

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.
