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.
