The power of the classification and knowledge (2)
High-power compensation type - purify type JingMiXing stabilizer) voltage stabilizer (including
It realized with compensation link the output voltage stability, easy to realize the microcomputer control.
Its advantages are anti-interference good performance, high precision (acuities avr + 1), fast response (40 ~ 60ms), circuit is simple, reliable work. Defect is: take the computer, pabx etc have nonlinear load frequency oscillation phenomena; Input side current distortion degree of big, the source power factor is lower; Output voltage of the input voltage have phase shift. Jamming function demand higher unit, in the city application advisable, computer power supply, must choose the computer total power around two to three times the regulator to use. Because of its regulator, anti-jamming, fast response, etc, so Craig moderate wide application.
Switch type interfluent stable power supply
It applied to high-frequency pulse width modulation technology, and generally switching power supply is the difference of its output must be and input side frequency, phase alexandrine. The output voltage ac voltage waveform a quasi square-wave, type wave, string wave, market uninterrupted power supply (UPS) removed one of the storage power and charger is a switch type, the interfluent stable power supply voltage, control functions of good strong, easy to realize intelligent, is very promising interfluent stable power supply circuit. Because of its complex, the price is higher, so the promotion slower.
