摘要： A connection-sensing DC plug has an insulative body, a connection portion, two power terminals, a conductive sheet and a retractable pin. The connecting portion is adapted to electronically connect to a target device and has an isolation layer and a ground layer. The conductive sheet is mounted in the insulative body and contacts either the isolation layer or the ground layer. The retractable pin is movably mounted in the insulative housing parallel to the connecting portion, with one end securely engaging the conductive sheet and the other end protruding from the insulative body. When the DC plug is connected to the target device, the retractable pin is pressed and moves inward to bend the conductive sheet, turning the conductive sheet to a floating state and resulting in a trigger signal.

摘要： A coil of a transformer has two side conducting brackets and at least one middle conducting bracket. The middle conducting bracket is elongated or spiral-shaped and has two terminals respectively connected to the side conducting brackets. The side conducting brackets and the at least one middle conducting bracket of some specific type are connected to form different numbers of loops or different types of circuits (series circuits or parallel circuits). Therefore, design and fabrication of the coil is flexible and materials and manufacturing costs are saved. Moreover, the side conducting brackets and the at least one middle conducting bracket require only two or four soldered joints so number of soldered joints required is limited and efficiency of the transformer is improved.

摘要： A switching power supply with the increased efficiency at light load has a switching power circuit, a power monitoring circuit and a light load power supplying circuit. The switching power circuit converts an AC power to a stable DC power and sends the DC power to a load according to voltage variation of the load. When the power monitoring circuit detects the AC power and determines that the load is in a light state, the power monitoring circuit controls the light load power supplying circuit to output a small-power DC to the load. As the DC power provided by the light load power supplying circuit is small, the switching loss ratio is lower in its light load state. Therefore, the operating efficiency at the light load state is higher.

摘要： A power supply having a two-way DC to DC converter has an AC to DC converter and a two-way DC to DC converter. When an AC power is input to the AC to DC converter, the AC to DC converter transforms the AC power to a middle level DC power and the two-way DC to DC converter transforms the middle level DC power to a low level DC power. When the AC power is unavailable and the two-way DC to DC converter obtains an external DC power, the two-way DC to DC converter transforms the external DC power to the middle level DC power. Therefore, if the power supply obtains the external DC power, the power supply can still output the middle level DC power even the AC power is unavailable.
