smart board panel

smart board panel.?At the front end of the charger, the AC mains voltage is rectified to generate the charger high voltage rail. Thus, the switching voltage component of the charger is superimposed on a sine wave of half the supply voltage. Similar to switching interference, this supply voltage is also coupled through a switching isolation transformer. At 50 Hz or 60 Hz, the frequency of this component is much lower than the switching frequency, so its effective coupling impedance is correspondingly higher. The severity of the supply voltage disturbance depends on the characteristics of the parallel impedance to ground and also the sensitivity of the touch screen controller to low frequencies.
