LIPS Board Block Diagram 12V 50 ~ 60Hz HVDC 100KHz 5V EMI INPUT RECTIFIER ENERGY OUTPUT RECTIFIER COMPONENTS AND FILTER TRANSFER AND FILTER LINE GND 100 ~ 240V PWM SIGNAL PHOTO- CONTROL COLLENTI COUPLER CIRCUIT ON ISOLATION PRIMARY SECONDARY 12V INVERTER CIRCUIT High Voltage output Operation description_LIPS 1. EMI components. This part contains of EMI components to comply with global marketing EMI standards like FCC, VCCI CISPR, the circuit included a line-filter, across line capacitor and of course the primary protection fuse. 2. Input rectifier and filter. This part function is for transfer the input AC voltage to a DC voltage through a bridge rectifier and a bulk capacitor. 3. Energy Transfer. This part function is transfer the primary energy to secondary through a power transformer. 4. Output rectifier and filter. This part function is to make a pulse width modulation control and to provide the driver signal to power switch, to adjust the duty cycle during different AC input and output loading condition to achive the dc output stablize, and also the over power protection is also monitor by this part. 5. Photo-Coupler isolation. This part function is to feed back the dc output changing status through a photo transistor to primary controller to achieve the stabilized dc output voltage. 6. Signal collection. This part function is to collect the any change from the dc output and feed back to the primary through photo transistor. 7. Inverter The inverter converts from DC12V to AC 700V and operate back-light lamp of module. To apply the AU Module. 3. ADAPTER BOARD (Component Side) 4. ADAPTER BOARD (Solder Side) To apply the HYDIS Module. 5. ADAPTER BOARD
