Manual Voltage Stabilizer Circuit

The next page covers the circuit and the construction details of this automatic voltage stabilizer circuit.

Manual voltage stabilizer circuit. It is a device or circuit which is designed to deliver constant voltage to the output without in changes in incoming voltage. Here i am presenting a circuit of auto cut that is used mostly in manual voltage stabilizer. The high low voltage protection circuit with time delay presented here is a. 6 circuit diagram of boost function in voltage.

This is a protection circuit that protects electrical appliances from high voltage. The zener diode has been connected directly across the load impedance z l hence the output voltage v 0 across the load impedance z l equals v z the zener breakdown voltage and is maintained almost constant impite of variations in either the input voltage v i or the load impedance z l. The common types of voltage stabilizers include manual operated or switchable stabilizers automatic relay type stabilizers solid state or static stabilizers and servo controlled stabilizers. The stabilizers sizes generally with its rating which is given in kva.

Referring to the figure click to enlarge we see that transistor t1 forms the main active part of the entire circuit. A voltage stabilizer is a device which is used to sense inappropriate. The presets p1 to p7 can be modified as per the needed tripping points which is able to correspond to the output ssr switching and the successive transformer tap. Figure 1 gives the basic circuit of simple simple dc voltage stabilizer using zener diode.

Boost function in a voltage stabilizer. This circuit connected with the output of the stabilizer. The suggested circuit of a basic 5 kva to 10 kva automatic voltage stabilizer circuit is simple to recognize. Whenever it detects over voltage in the primary supply the connection of the load is manually automatically shifted to the buck mode configuration with the help of switches relays.

The project posted here is of called automatic voltage stabilizer circuit which solves almost all problem faced in normal available stabilizer efficiently. Existing automatic manual stabil izer and. There s switching circuit in the voltage stabilizer. Fig 1 shown below are the block diagram and circuit diagram of the voltage stabilizer connected to an appliance or load.

With the help of automatic voltage stabilizer circuit we are able to keep constant voltage at 230v when voltage goes low as 170v and high as 250v automatically. The functioning of this simple voltage stabilizer circuit may be understood from the following points.
