摘要： A power supply device has a first output port, a second output port and a power delivery control module. The power delivery control module compares the first output voltage value and the second output voltage value to determine a reference voltage value, and determines the optimized voltage value according to the total output power value, the reference voltage value, and a rated output current of an AC/DC converting module. The power delivery control module controls the AC/DC converting module to convert the AC input voltage to an optimized voltage, so that when the first and second DC/DC converting modules receive the optimized voltage and convert it to the first and second output voltages respectively, the voltage drop is reduced, the conversion loss is reduced, and the conversion efficiency of the power supply device is improved.

摘要： A redundant power supply system has power supplies and holdup control circuits. The power supplies are connected in parallel for connecting to an input capacitor of a load system. An OR-gate anti-reverse current element is connected between each of the power supplies and the input capacitor. The holdup control circuits correspondingly connect to the DC output sides of the power supplies. Each of the holdup control circuits has an inductor, an electronic switch and a controller. The inductor is connected in series to the OR-gate anti-reverse current element. The electronic switch is connected between the DC output side of the corresponding power supply and a node where the inductor and the OR-gate anti-reverse current element are connected. The controller turns on and off of the electronic switch according to the DC power output from the DC output sides, thereby prolonging the holdup time after a power failure.

摘要： A power supply device includes a power output terminal, a power converter and an electronic circuit breaker. In view of operation of the electronic circuit breaker, when an electric appliance that acts as a load is connected between the power output terminal and a ground terminal, the electronic circuit breaker is activated to output voltage from the power converter to the power output terminal so as to charge the electric appliance. When the electric appliance is done with charging and is removed, the electronic circuit breaker is deactivated to prevent voltage of the power converter from being outputted to the power output terminal. Thus, even if the power output terminal is exposed, the power output terminal won't output power to result in electric shock because of users' inadvertent contact when no electric appliance is being charged, thereby enhancing operational safety.

摘要： The present application is a converter having a low loss snubber. The low loss snubber of the converter includes a clamping winding, a first capacitor, and a second capacitor. The clamping winding is magnetically coupled with a primary winding of a transformer of the converter. The primary winding to a secondary winding of the transformer leakage inductance energy is recovered by storing the energy in the second capacitor. When the second capacitor is discharging, the energy in the second capacitor may be further transferred to the first capacitor. When the first capacitor is discharging, energy in the first capacitor may be further returned to the power source. Therefore, the energy in the first capacitor and the energy in the second capacitor may not be consumed by a resistor, and power consumption of the low loss snubber may be decreased.

摘要： A universal power supply system allows each board mounted DC power module or each AC/DC power supply device therein having identical dimensions and appearance to further have a specification setting circuit. When the board mounted DC power module or the AC/DC power supply device is plugged in a backboard module, the specification setting terminal outputs a specification identification signal to a monitoring circuit of the backboard module. As built in with a specification mapping table, the monitoring circuit can compare the specification identification signal to find a model number corresponding to the signal, and automatically sets a critical current value or critical power value of each board mounted DC power module for over-current protection or over-power protection. Accordingly, the universal power supply system can be adapted to different board mounted DC power modules or AC/DC power supply devices without redesigning the backboard module.

摘要： A symmetric planar transformer having adjustable leakage inductance has a circuit board, two first bobbins mounted respectively on opposite side surfaces of the circuit board, two primary windings mounted respectively on the first bobbins, two secondary windings disposed respectively between the circuit board and the first bobbins, two second bobbins disposed respectively between adjacent first bobbins and primary windings, two pad sets disposed respectively between adjacent first bobbins and second bobbins, and a magnetic core assembly mounted through the circuit board, the first and second bobbins, the secondary and primary windings and the pad sets. Adjusting the numbers of the at least one pad of each pad set also adjusts distances between the primary and secondary windings to allow the secondary windings to have the same leakage. Thus, a balanced electric current is induced.

摘要： A packaged heat dissipating assembly for an intermediate bus converter (IBC) has a frame being mounted on and around the IBC and a heat sink being mounted on the frame. The packaged heat dissipating assembly is easily detached from the IBC. Therefore, a broken bus converter module (BCM) or heat sink is easily replaced separately. Consequently, heat dissipating designs and maintenance of a server or communication equipment is facilitated and maintenance costs of the IBC and the server or communication equipment are lowered.

摘要： A universal input switching power supply has a signal detecting unit, two DC converting units and a physical wiring and controlling unit. The DC converting units are respectively adapted to couple to an AC power source to convert the AC power source to two first DC power sources and changes a voltage of each of the first power sources according to different voltage of the AC power source. The physical wiring and controlling unit is connected to the outputs of the DC converting units and the signal detecting unit and automatically connects the outputs of the PFC circuits in parallel if a high line voltage range of the AC power source is coupled to the full bridge rectifier. On the contrary, the physical wiring and controlling unit automatically connects the outputs of the PFC circuits in serial. Accordingly, the universal input switching power supply has good transmitting efficiency at different AC power source conditions.
