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 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.
