Of course many types of exchange regulator, the main circuit works differently, but basically (AC parameter regulator exceptions) basically input switch sampling circuit, a control circuit, a voltage regulator, output protection devices, drives, monitors and and composition.
1, input switch: as exchange regulator input operating switch, generally used current limiting protection of air switch Miniature circuit-breaker, it can on the exchange regulator and electrical equipment protection.
2, the voltage regulating device: is a way to regulate the output voltage of the device, it will raise or lower output voltage AC voltage regulator is the most important part.
3, the sampling circuit: its exchange regulator output voltage and current detection, the situation will change in the output voltage to the transmission to the control circuitry.
4, Drive: electrical control circuit because the control is weak, so they need to use the drive for power amplification and conversion.
5, the drive protection devices: a communication device output and disconnect the AC regulator, commonly used relay or contactor or insurance and so on.
6, the control circuit: it is sampling circuit detects the models for analysis, when the output voltage is high, the voltage control signal is sent to the lower drive unit, the drive means driving voltage regulating means lower output voltage when the output When the voltage is low, is sent to the drive control signal voltage increases, the driving means driving voltage regulating means to increase the output voltage, output voltage stability leaving achieve a stable output purposes.
When detecting the output voltage or current exceeds the exchange regulator control. The control circuit controls the output protection device to make it off the output and protection of electrical equipment, while the output in normal output protection device is connected, electrical equipment can be a stable voltage supply.
