    Abstract: A power-saving charging device controls both a primary side controller and a secondary side controller to be in a shutdown state when an output terminal is not connected to the load. When the output terminal is connected to the load, the secondary side controller receives a power-on power supply from a power storage unit, performs a power-on procedure and enters a working state. The primary side controller receives a power-on signal from the power storage unit, performs the power-on procedure according to the power-on signal, and enters the working state. Accordingly, when the charging device is not connected to the load, it can enter a standby state with extremely low power consumption in which the primary side controller and the secondary side controller are both turned off, thereby achieving the effect of saving the power consumption of the controller when the charging device is in standby.

    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 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.

    Abstract: 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.

    Abstract: A power supply has a power factor correction (PFC) circuit and a DC to DC conversion circuit. A DC to DC controller of the DC to DC conversion circuit acquires zero-crossing information and load information from the PFC circuit through a communication protocol, and performs a low-frequency compensation on a control command using a table-mapping means, thereby resolving the issues of higher controller complexity, changes of entire response characteristics and cost increase in conventional compensation technique.

    Abstract: A switching power supply with a resonant converter has an AC to DC converter and a DC to DC converter. The AC to DC converter converts an inputted AC power into a DC power. The DC to DC converter has a resonant converter determining a current operating state according to waveforms of a transformer voltage and a driving signal actually measured and further controlling a switching frequency of the resonant converter to approach or to be equal to a resonant frequency for operational efficiency enhancement. Accordingly, the failure to accurately calculate a resonant frequency beforehand can be solved and the issue of accurately keeping the switching frequency consistent with the resonant frequency can be tackled.
