Civil power (100-240V AC are adapted to global voltage) passes through fuse F1 (short-circuit protection), piezo-resistance VR1 (surges
Protection), after EMI circuits (LF1, LF2 and CX1) filter out conduction and radiation interference, into rectifier bridge DB1 rectifying parts, after rectification
After being filtered by high pressure low volume electric capacity C16, become pulsating dc voltage and enter pfc circuit and power conversion circuit.SN03 is controlled
Device processed is to integrate PFC adjusters and the single- stage PFC controller of PWM controller, i.e. pfc circuit and power conversion circuit shares
A set of circuit, the primary winding of power conversion part both primary side as power conversion, again the boosting electricity as PFC
Sense.

B Phototube Couplings, the different dutycycle of control PWM controller output pulse width, the triode Q1 for changing power inverter are opened or closed
The time is closed, so that output voltage reduces or rise so that the output voltage stabilization of power supply.
The alternating voltage that power inverter secondary (secondary) induces is by diode D3, electric capacity C10A, electric capacity C10B
Filtering forms steady dc voltage and enters U3 (78U05), and U3 is a switch power module, can withstand up to 72V direct current
