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 power supply with a staggered configuration includes a housing having an accommodation space, a first power supply module, a second power supply module, and an electric fan which are disposed inside the accommodation space. The first power supply module includes a first frontend power conversion unit and a first backend power conversion unit which are disposed at separate airflow passages. When the power supply is in operation, the electric fan turns and drives the air to flow into the housing in such a way that one airflow passage is through the first frontend power conversion unit and another airflow passage is through the first backend power conversion unit. In this way, the heat dissipation efficiency is increased with two separated air flow passages respectively flowing through and cooling down the first frontend power conversion unit and the first backend power conversion unit.

摘要： A DC converter includes a non-isolated conversion module and an isolated conversion module. The non-isolated conversion module is implemented based on a redundant structure and has a first power conversion loop, a second power conversion loop, and an energy storage element. The first and second power conversion loops are connected and share the energy storage element. The energy storage element is further connected to an input terminal of the isolated conversion module. The first and second conversion loops of the non-isolated conversion module convert DC power outputted from two battery sets and output the converted power to the isolated conversion module. The isolated conversion module further supplies DC power to a load. Accordingly, power supply systems using the foregoing DC converter can reduce the number of transformer therein and thus size reduction of the power supply system can be achieved.

摘要： A filtered connector is mounted on a casing and includes a connection port and a filter board. An electrode plate mounted on one end of the connection port and electrically isolated from the casing is securely mounted through a through hole of the casing. The filter board has a circuit board assembly, multiple grounding spring plates and multiple filtering capacitors. The circuit board assembly has a slot to be mounted through by the electrode plate. The grounding spring plates are mounted on a surface of the circuit board assembly and electrically contact the casing. The filtering capacitors are electrically connected between the electrode plate and the grounding spring plates. As the filter board is not mounted inside the connection port, only the filter board is to be mounted without replacing the connection port, thereby lowering users' expense in installation of the filter board.
