5.2 PWPC board

5.2.1 Block diagram

PWPC board combines to adapter and inverter, this design has the merits in predigesting

constructions, reducing cost and improving product’s capability.

Adapter which commonly consists of bridge rectifier and filter, start circuit, PWM control circuit

(TOP247Y), protection circuits and convert to 12V, 5V DC voltage by input 90V-240V AC voltage that provide

power supply for each chips in the main board and inverter.

Inverter is DC TO AC circuit. It changes the 12v DC of power supply to about 600-800v AC that drives

the backlight. It mostly consists of starting circuit, PWM controller, output circuit and protection circuit etc.
