The parameter-adjustable voltage stabilizer is suitable for departments with special requirements for reliability and anti-interference performance.

Advantages: high reliability; high-energy interference resistance; no output overvoltage phenomenon; wide input voltage range; good overload performance (strong overload capacity of ferromagnetic components); can be made into high-power power supply equipment.

Disadvantages: bulky, consumes a lot of copper and iron materials, so the price is high; the consistency of mass production is poor (influenced by the core material and process); the source power factor is low and the efficiency is also low; the load adaptability is poor (influenced by the nature of the load) Voltage regulation accuracy); poor frequency effect (ferromagnetic resonance is very sensitive to source frequency changes); large output voltage distortion, output voltage and input voltage have a phase shift (due to the non-linearity of the iron core); the temperature rises, the noise is large (the iron core saturation, large leakage inductance). Automatic voltage regulator, suitable for departments that do not require response time.

Advantages: wide input voltage range (using the characteristics of long brush stroke); the output voltage waveform is the same as the input voltage waveform, and the phase is the same; the whole machine has high efficiency (the loss of the self-operating voltage regulator is small, and the general efficiency is more than 95); The load has good adaptability; it is easy to manufacture, low cost and cheap; it can be made into a high-power compensation power supply.

Disadvantages: Short working life (due to brush wear); long response time (slow action due to mechanical transmission).

Purification type voltage stabilizer, suitable for units with high requirements for anti-interference function.
Advantages: good anti-interference performance; high voltage regulation accuracy (better than ±1); short response time, that is, fast response speed (40-6Oms); simple circuit and reliable operation.
Disadvantages: with nonlinear loads (computers, etc.) sometimes there is low frequency oscillation; the input side current distortion is large, the source power factor is low; the output power supply has a phase shift to the input voltage.

Compensated voltage stabilizer, suitable for making power voltage stabilizers that do not require high load properties.

Advantages: fast response speed (because power tube is used as switching device); can be made into a high-power model; output voltage distortion is small (no additional distortion in the machine); high efficiency.

Disadvantages: The power semiconductor devices in the machine may fail, affecting the reliability of the power supply equipment.
