摘要： New and Useful magnetic structures are provided. One feature of the magnetic structures is that they are configured to help minimize the air gap reluctance, improving the magnetic structure's coupling coefficient. Another feature is that reducing the windings AC impedance of a magnetic structure is produced by shielding the winding under ears formed of magnetic material. Still another feature is that leakage inductance of a magnetic structure is reduced, by making ears with cuts which converge toward the magnetic rods that are used in the formation of the structure.

摘要： A power adapter includes a power converting circuit, a current detecting circuit, and a controlling unit. A charging voltage with a constant voltage level is provided by the hub through the connecting ports. The current detecting circuit is used for detecting a load current and outputting a corresponding current detecting signal. The load current is transmitted from the power converting circuit to the hub through the power cable. A look-up table is stored in the controlling unit for recording a relationship between the load current and a voltage drop across an impedance of the power cable. According to the current detecting signal and the look-up table, the controlling unit issues a feedback signal to the power converting circuit. According to the feedback signal, a level of the output voltage is dynamically adjusted to be equal to the sum of the voltage drop and the charging voltage.

摘要： A cable winding device comprises a case, a reel disc, a cable, and a cable locking structure. The case comprises a first case element and a second case element. The reel disc is disposed between the first case element and the second case element, wherein the reel disc has a leaf spring. The cable is wound on the reel disc. The cable locking structure has a fixing part and at least partially penetrates the first case element and the reel disc. When a pulling operation of the cable causes the leaf spring to be sustained against the fixing part, a desired length of the cable is pulled out from the case and locked. When the cable locking structure is pressed and the fixing part is detached from the leaf spring, the cable pulled outside the case is rewound on the reel disc.

摘要： Disclosed is an overload protection delay circuit for use in a switching power supply for enabling the switching power supply to detect overload problems with high accuracy. The overload protection delay circuit is connected between a photo coupler and a pulse-width modulator of the switching power supply, and is consisted of an energy storage device such as a capacitor and a charging controller such as a zener diode. The charging controller is configured to set a limit value for allowing the energy storage device to be charged by an internal current source of the pulse-width modulator when the feedback signal of the switching power supply reaches the limit value. By charging the energy storage device, a time delay is added to the feedback signal so that the pulse-width modulator can accurately activate the internal overload protection mechanism without the interference of load transients.
