1. Classification By Use:

• Power Voltage Stabilizer:

Mainly used to stabilize the output voltage of the power supply and provide a stable power supply voltage for various electronic equipment and electrical appliances. Such as computer power voltage stabilizer, laboratory power voltage stabilizer, etc., to ensure that the equipment works normally under a stable voltage and protect the equipment from damage caused by voltage fluctuations.

• Signal Voltage Stabilizer:

Used to stabilize the amplitude of the signal, in the fields of communication, measurement, etc., to ensure the stability and accuracy of the signal during transmission. For example, in some weak signal detection systems, the signal voltage stabilizer can stabilize the weak signal at a suitable amplitude, which is convenient for subsequent signal processing and analysis.

2. Classification By Working Mode:

• Linear Voltage Stabilizer:

Like the above-mentioned linear DC voltage stabilizer, its advantages are high output voltage accuracy and small ripple, and its disadvantage is relatively low efficiency, because the adjustment element works in the linear region, which will consume a certain amount of power and generate heat.

• Switching Voltage Stabilizer:

Including the above-mentioned switching DC voltage stabilizer, it has the advantages of high efficiency, small size, light weight, etc., because the switch tube works in the switching state, the loss is small. However, the output ripple of the switching regulator is relatively large, and a better filtering circuit is needed to reduce the impact of the ripple on the load.

• Parametric Regulator:

It works on the principle of ferromagnetic resonance, and through special circuit structure and component parameters, the output voltage is kept stable within a certain range. The parametric regulator has the characteristics of strong anti-interference ability and good overload capacity, but it is large in size and relatively slow in response speed.
