1, input RC damp, use at absorbing to input signal of high frequency interference; 2, switch on the mobile phone prevent surge to input voltaic resistor; 3, input in all modular interference filter divides inductance; 4, output rises voltage inductance, this circuit rises way of positive electricity of school of factor of voltage active power to apply extensive output; 5, output starts diode, when circuit output has not achieved normal output when voltage, communication inputs town report commutate to output volts d.c. to be laden power supply through this diode, once circuit works normally, it is normal that output voltage is achieved, this diode closes, do not work; 6, positive electricity of power factor school sheds sampling resistor, carry the control action of circuit, make communication inputs electric current to weaveform is and communicate voltage of input town report to be the same as the sine wave with inphase frequency, achieve power factor corrective action; 7, corrective power switch is in charge of power factor the RD drive circuit of Q1, make in drive signal Q1 guides when connecting, diode D7 does not work, when Q1 closes, the input capacitance of Q1 passes D7 guide, make the input capacitance of Q1 accelerates discharge through R10 and R9 loop, make Q1 enters cycle of next switch job smoothly thereby; 8, the RC of IC amends return, make IC stabilizes the job; 9, output rises canal of voltage power switch; 10, RC draws return circuit, use at reducing output to rise the power comsumption on voltage diode; 11, D3 rises voltage diode for output; 12, cent of resistor of output voltage sampling presses circuit, voltage of output voltage sampling remands of IC the 6th bring a foot to do output voltage feedback, make output voltage stability; 13, cent of resistor of sampling of voltage of output overvoltage protection presses circuit, once circuit appears,output overvoltage breakdown, circuit protection closes output; 14, capacitance of output filter wave, capacitance of generous of a look and a look hidebound capacitance are shunt-wound, the capacity outputs action of voltage filter wave since big capacitor, stability outputs voltage, look hidebound capacitance is used at filter to remove high frequency interference, general high capacity electroanalysises the high frequency character of capacitance is bad, look hidebound capacitance is used at improving high capacity to electroanalysis the wave of high frequency filter of capacitance is characteristic; 15, capacitance of wave of filter of PFC corrective input, use at filter to divide an input high frequency interference, the capacity shoulds not be too big, can affect the result with power corrective factor otherwise; 16, output release resistor, once export laden open a way, use at discharge dropt to output the charge on filter wave capacitance.
