Block Diagram Of Voltage Regulator

Lm340 series voltage regulator.

Block diagram of voltage regulator. It is available in two types which are compact and used in low power low voltage systems. When we utilize an external transistor then it supplies 10a current to drive the load. There are mainly two types of voltage regulators. The block diagram of transistor series voltage regulator is shown in above figure.

It is also used to regulate or vary the output voltage of the circuit. There are many stages of voltage gain for the op amp used here. The unregulated ac voltage is connected to a transformer which steps that ac voltage down to the level for the desired dc output. In the transistor series voltage regulator the control element is connected in series with the load due to this circuit is known as series voltage regulator.

The output from an ordinary power supply is fed to the voltage regulating device that provides the final output. Voltage regulator circuit to get constant dc output voltage. These are used in wider applications. When the control element is in series with the load the output is given by.

Compensates for variation in the mains line voltage stabilization. By aneta veers on october 03 2019 in wiring diagram 210 views. Linear voltage regulators and switching voltage regulators. There are two main types of dc voltage regulator.

To maintain the constant current by making use of control element some current is shunted away from the load. The block diagram of shunt voltage regulator is shown below in this type of voltage regulator in order to provide adequate regulation the current is shunted away from the load. Series voltage regulator a sampling unit. As shown in the block diagram above the built in reference voltage vref drives the non inverting input of the operational amplifier.

The voltage regulator using lm340 ic is the most used voltage regulator ic. V out v in v s. Linear voltage regulator is the easiest type of voltage regulators. Lm723 ic is a changeable voltage regulator used in the series regulator application with 150ma current op without exterior pass transistor.

Regulated power supply block diagram a regulated power supply essentially consists of an ordinary power supply and a voltage regulating device as illustrated in the figure. The block diagram of basic series dc voltage regulator is shown in figure which is consisting of four stages. Compensates for variation in load current however in practice both the terms loosely used for the same meaning of voltage regulation.
