    摘要: A heat dissipating structure of a power supply is disposed on an inner side of a casing and has two heat dissipating covers configured to be connected with each other, and a heat dissipating sleeve annularly mounted on and around the two heat dissipating covers and disposed between the heat dissipating covers and the casing. The heat dissipating sleeve is able to be bent according to an internal structure of the casing for attaching to the casing and increasing contact area between the heat dissipating sleeve and the casing. The heat from an interior of the power supply can be conducted to the two heat dissipating covers for a first heat spreading and then to the heat dissipating sleeve for a second heat spreading. Thus, speed of heat dissipation to an exterior of the casing can be increased and temperature inside the power supply can be effectively reduced.

    摘要: A power converter with an adjustable output voltage has an isolation DC/DC transformer, a primary side circuit connected to a primary coil of the isolation DC/DC transformer for transmitting an input AC power to the primary coil, and a secondary side circuit connected to a secondary coil of the isolation DC/DC transformer. The secondary side circuit includes a first output loop, a second output loop and a mode switch connected in the first output loop. When power consumption of a load is low, the mode switch is turned off to interrupt the first output loop so that the secondary side circuit generates a first output voltage with a low voltage level. When power consumption of a load is high, the mode switch is turned on and the secondary side circuit generates a second output voltage with a high voltage level. Without greatly increasing circuits, the power converter achieves wide-range voltage regulation.

    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 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.
