Introduction

Voltage regulator is a device which supports with defined precision constant voltage across the load. Change the load voltage may be due to several reasons: voltage fluctuations initial power supply (mains, battery, galvanic cell), load changes, changes in ambient temperature, etc.

According to the principle of distinguishing parametric and Countervailing stabilizers. In turn, these stabilizers can be odnokaskadnymy, multistage and bridge.

Compensation stabilizers can be with continuous or pulsed control; or that may be serial or parallel type.

Parametric voltage stabilizers perform stabilization by varying the parameters of semiconductor devices: diodes, stabistoriv, ​​transistors, etc. Variables semiconductor voltage regulators is their own resistance and conductivity.

Compensation stabilizers are a closed system of automatic voltage regulation at the load, made using semiconductor devices. Output voltage stabilizers such as supported equal or proportional supporting stable voltage, which formed one of the types of parametric stabilizers.

Compensation containing stabilizers composed of control element (in most cases transistor) which can be connected in series or in parallel to the load.

The control element can operate in continuous mode or key. Switching Regulators used in a key mode of regulatory elements, and stabilizers with continuous control - continuous.

Support for the accuracy of the output voltage at the load stabilizers divided into precision (voltage change no more than 0.005%), accurate (voltage change of 0.01% to 0.005%) average accuracy (voltage change from 0.1% to 0.01%), and low accuracy (voltage change of 1% to 0.1%).

Electric power has a specific set of properties that are identified as electricity generators, and enerhoperedatchykamy. Options electricity determining its quality and features. Consumers of electricity can operate at certain (nominal) parameters of electrical energy. Normal operation of electricity consumers AC provided mainly while in the nominal voltage range, frequency and form of sinusoidal signal.
