Parameter-adjustable voltage regulator is suitable for departments that have special requirements for reliability and anti-interference performance.
Advantages: high reliability; resistance to high-energy interference; no output overvoltage; wide input voltage range; good overload performance (ferromagnetic components have strong overload capability); can be made into high-power power supply equipment.

Disadvantages: heavy, consumes a lot of copper and iron materials, so the price is higher; batch production consistency is poor (affected by core material and process); source power factor is low, efficiency is also low; load adaptability is poor (affected by load properties) stable
voltage 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 core nonlinearity); temperature rise, large noise (core saturation ,leak
Feeling great).
Automatic voltage regulator is suitable for departments that do not have response time requirements.
Advantages: wide input voltage range (taking advantage of the long stroke of the brush); the output voltage waveform is the same as the input voltage waveform, and the phase is consistent; the overall efficiency of the machine is high (the loss of the self-made voltage regulator is small, and the general efficiency is above 95); It has good adaptability to load properties; is easy to manufacture, low cost and inexpensive; and can be made into a high-power compensation power supply.
Disadvantages: short working life (due to brush wear); long response time (due to mechanical transmission and slow movement).

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

Compensation voltage stabilizer is suitable for making power voltage stabilizers that do not have high requirements on load properties.
Advantages: fast response speed (because power tubes are used as switching devices); can be made into high-power models; low output voltage distortion (no additional distortion in the machine); high efficiency.
Disadvantages: The power semiconductor devices in the machine may malfunction, affecting the working reliability of the power supply equipment.
