摘要： A power supply system drives a plurality of loads, and includes a power stage circuit, a pulse width modulation controller, a first isolation transformer, at least two second transformers, and at least two rectifier circuits. The power supply system converts external power signals into first alternating current (AC) power signals, and converts the first AC power signals into second AC power signals. The second transformers either boost or buck the second AC power signals, and each has a primary winding connected to a secondary winding of the first isolation transformer in parallel and a center tap grounded. Each of the rectifier circuits is connected to two ends of a secondary winding of a corresponding one of the second transformers, and rectifies the boosted or bucked second AC power signals to output direct current (DC) power signals to a corresponding one of the plurality of loads.

摘要： A pen for the touch pad of a laptop includes a conductive penholder, wherein a conductive pen head is installed on one end of the conductive penholder, and a smooth layer is located on the surface of the conductive pen head. The conductive pen can deliver the static electricity from a human's body through the conductive pen to the touch pad of a laptop computer. It replaces the original operation in which a user uses their finger to touch the touch pad of the laptop. It is convenient for the user and the user can operate it for a long time. The problems caused by the user's sweat re avoided. The opposite end of the conductive penholder can be installed with a PDA pen, a ball-point pen, a laser, or a pencil. The function of the present invention is therefore versatile.
