The monitor consists of the lamp tube and DC/AC convertor (DAC). DAC consists of the impulse width modulation unit (IWM), the DC/DC conversion unit (DDC) and the self-oscillation circuit (SO). IWM outputs the PWM signal. The impulse width of the PWM signal is decided by the level signal. Receiving the 1st DC voltage, DDC converts it into the 2nd DC voltage. The level of the 2nd DC voltage is decided by PWM signal. According to the 2nd DC voltage, SO produces the AC voltage and sends it to the lamp tube. According to the level signal, the DC/AC converter defines the level of output AC voltage. When DAC works under the burst mode, the level signal is an interlaced hi and low level to cause the output AC voltage burst.
