JW (JSW) - series precision purifying AC power supply system technology introduction JJW (JSW) - series precision purifying AC power supply with international advanced sinusoidal energy distribution power conditioning technology program, combined with efficient design and integrated broadband filter network a. Represents the latest development of AC voltage regulator technology, the main circuit by the sinusoidal power splitter and power filters connected in parallel, when the mains input voltage or load current changes, sinusoidal energy distributor in a half cycle sine current form, the energy input to precise as required inductor, inductor to adjust inductance to ensure stable output voltage with high accuracy. Fig. K is the control switch, controls the entire power supply on and off; J is a relay, when power supply to operate normally, overpressure, undervoltage, overload and other reasons, to provide power protection, C1, C2 and TA and inductor L1 constitute sine energy distribution circuit whose famous works generally: autotransformer TA, tap connected to the input power U1, the inductor L1 and the lower end of the triac S then auto transformer by controlling the triac the size of the conduction angle, change the inductance L1, and to adjust the output voltage. JJW (JSW) precision purifying AC power supply control circuit is a sawtooth formation mains synchronization circuit, output voltage sensing circuit comparing circuit trigger part of the circuit and protection circuit. Output feedback output voltage sampling circuit size (converted into direct current), with the sawtooth voltage comparison, the pulse signal generated after comparison to the trigger to trigger triac, by changing the △ U resize the output voltage.
