ABSTRACT:
A switching type AC adapter includes a current mode PWM (pulse-width-modulated) controller, a monostable multivibrator, and a MOSFET so arranged that the current mode PWM controller and the monostable multivibrator are operated to let switching of the MOSFET be synchronized to synchronous signal from a synchronous circuit when the switching type AC adapter is electrically connected, enabling horizontal synchronizing interference to be concealed behind retrace time, and kept away from the screen of video equipment in which the switching type AC adapter is installed.
