LIPS Board Block Diagram 12V 50 ~ 60Hz HVDC 100KHz EMI COMPONENTS INPUT RECTIFIER AND FILTER ENERGY TRANSFER OUTPUT RECTIFIER AND FILTER 5V GND LINE 100 ~ 240V PWM CONTROL CIRCUIT PHOTO-COUPLER ISOLATION SIGNAL COLLECTON 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 for 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 achieve the dc output stabilized, 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 - 15 - ADJUSTMENT Windows EDID V1.0 User Manual Operating System: MS Windows 98, 2000, XP Port Setup: Windows 98 => Don't need setup Windows 2000, XP => Need to Port Setup.
