It designs with the piezoresistor VDR. A special RCD surge absorption circuit (A M7 and a resistor parallel, and then series a 4.7uF/400V electrolytic capacitor, connect to GND) is after the rectifier bridge. And the primary and second transformer is synchronous design of RCD absorbing circuit. And there is a Y capacitor connecting to GND of primary and second (Y capacitor according to the actual condition, to select to install, or not.)it is stronger to anti-surge capacity then the ordinary one. 3. All the module PF value can be improve, according to reduce the value of CBB capacitor on C1, easily. Test Report: No. V IN (VAC) V OUT (V) I OUT (ma) PF P OUT (W) P IN (W) Eff.

5 Transformer specification: Transformer parameter: Frame: EEFD20 horizontal 4+4P Magnetic core: PC40 1. Primary inductance (Pin3 Pin4 ): Lp =0.85mH, ±5% 2. Primary leakage inductance (others PIN be short,test Pin3-Pin4 inductance) L K <50uH(@10kHz) 3. Primary winding turns (Pin3 Pin4):Np= 120Ts 4. Auxiliary winding turns(pin1 Pin2):N AUX =19Ts 5. The secondary winding turns(pin8 Pin5):N S =68Ts 6. Magnetic core need connect the GND of primary(magnetic core need connect to the PIN2 of transformer(primary)) 7. The transformer must vacuumizing, and then penetrating oil, dry it in high temperature.(it should be not any bubble after been dry) The dry transformer require it can accept 3.6Kvac 50HZ, leakage current less then 5mA high voltage test(high voltage test method: be short the pin which on the each side of the transformer, one side be a group. Put one group to the positive of the high voltage equipment, another group to negative, and then test it in high voltage.)(when you do the high voltage test, you should confirm the insulating oil be dry and cooling.) 8. Transformer labeled:10-18x1w

Pin1-Pin2,Φ0.15mm*2,19Ts 7 Auxiliary winding Φ0.15mm enamelled wire,wind begin on Pin1,wind N AUX (1 layer) one layer in 19 circle with double wires,finish at Pin2. 8 Insulation adhesive Add two layers insulation adhesive 9 Pin7-Pin4,Φ0.28mm,40Ts Primary winding Single Φ0.28mm enamelled wire,wind begin on Pin7 Np(1 layer),40 circle for one layer,finish at Pin4. Note: a) Winding arrangement agreement, penetrate enamel in vacuum, put off the useless Pin. b) Magnetic core connect the GND, in the end(magnetic core connect to the transformer Pin2 (Primary GND))
