Structure of stabilizer:

A current stabilizer is a power supply that maintains a stable output current. The Rs in the circuit are called signal sampling resistors. By adjusting the base current of the transistor or keeping the voltage on R constant, the stability of the output current is ensured. Changing R can change the output current. In order to maintain stable current even when the output current is very small, a resistor can be connected in parallel at the output end. In order to reduce the temperature coefficient of the output current, a low-voltage regulator with a negative temperature coefficient can be selected to compensate for the changes in output current caused by the negative temperature coefficient of transistor UBE. When the output terminal of the series regulator is changed to Rs, as long as the load is connected to one end of the input voltage and connected in series in the main circuit, it can become a stable current power supply.

StabilizerWorking Principle:

A current stabilizer is used to stabilize the filament current in an electronic tube. A stabilizer is two iron wires placed in a tube containing hydrogen and fluorine. When the voltage at both ends of the current stabilizer increases within a known range, its resistance also increases to the extent that the current passing through the stabilizer remains almost constant. In fact, when the voltage change at both ends of the stabilizer is greater than twice, the overall change in current is not greater than 5%.

StabilizerPurpose and significance:

The purpose of a current stabilizer is to provide a stable current to the circuit, ensure that the machines in the circuit can operate normally, and extend their service life. The main reasons for changes in output current are changes in input voltage and load.

StabilizerAdvantages and disadvantages:

Advantages: Fast control and adjustment response speed, high efficiency, small size, convenient and simple application, constant output current

Disadvantages: Large output pulsation and high ripple value
