Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A redundant power system has a first power supply and a second power supply. The first power supply has a first controller with a first communication port and a first I/O port and has a normal mode, a master mode and a slave mode. An external device can send a mode setting command to the first controller through the first communication port.

Abstract: A transformer has two magnetic cores, at least one primary winding unit mounted in the magnetic cores, at least one secondary winding unit mounted in the magnetic cores and two rectifying circuit boards externally mounted beside the magnetic cores. An AC voltage output from the secondary winding unit is transmitted to and rectified by the rectifying circuit board. Therefore, the size of the transformer is compact, and heat energy generated by electronic elements mounted on the rectifying circuit board is effectively dissipated to maintain normal operation of the transformer. Further, since the transmission path from the secondary winding unit to the rectifying circuit board is short, energy loss is reasonably reduced when the transformer is operated under a high frequency situation or a larger current mode.

Abstract: A power supply has a housing, a circuit board, a wire, and a wire securing assembly. The wire securing assembly has a base plate and a securing structure. The securing structure has a first plate and a second plate. A side edge of the first plate is connected to the base plate. The second plate is spaced apart from the first plate. The wire is mounted through and between the first plate and the second plate. The wire securing assembly is modified from the current insulating part, in which the original side plate extends and forms an additional part, or a bent structure is added on the original side plate, and thus the additional structures become the securing structure. Thus, the wire is prevented from moving under vibration or external force and contacting the blades of the fan, or keeps in a position in compliance with safety requirements.

Abstract: A D-mode GaN transistor synchronous rectifier of the present invention includes a power switching module, a peak detection module, and a gate driver module. The peak detection module stores energy when the negative end of the secondary side winding of the power converter is at a high voltage. The power switching module includes a first switch and a D-mode GaN HEMT as a second switch connected in series. The energy is provided to the module gate of the power switching module through the gate driver module to keep the first switch turned on. The gate driver module conducts the module gate and the module source when the positive end of the secondary side winding is at a low voltage, such that a clamp circuit pulls the gate-source voltage of the second switch below threshold and turns it off. The synchronous rectifier replaces conventional diode rectifier, having lower conduction loss and response ringing.
