Abstract: An inductor module includes at least one first magnetic core, a second magnetic core and at least one winding assembly. Each first magnetic core includes a connection part, a first post and a second post. The first post and the second post are disposed on a top surface of the connection part. A winding groove is formed between the first post and the second post. The second magnetic core is disposed adjacent to the first magnetic core. Each winding assembly is formed by wrapping a single metal sheet for at least one turn. Each winding assembly is disposed around the first post. A portion of each winding assembly is accommodated within the winding groove of the corresponding first magnetic core. An overall thickness of the winding assembly within the winding groove is smaller than or equal to a width W of the winding groove and greater than 0.9×W.

Abstract: A magnetic element is provided and includes a first magnetic core, a second magnetic core and two windings. The first magnetic core is made of a first material and includes two winding pillars and two connecting parts. The first magnetic core has a first permeability. The second magnetic core is made of a second material and has a second permeability. The first permeability is less than the second permeability. When the current flows through the two windings, a closed magnetic path is generated in the first magnetic core, the magnetic flux generated by the closed magnetic path flows through one of the winding pillars, one of the connecting parts, the other one of the winding pillars and the other one of the connecting parts in a direction, and the magnetic fluxes generated on the second magnetic core are cancelled out by each other.

Abstract: A power backup circuit provides a plurality of input power sources to back up a load. The power backup circuit includes a first switch, a second switch, and a control unit. The input power sources at least includes a first input power source and a second input power source. If the input power source of the load needs to be changed from the first input power source to the second input power source, the control unit controls the first switch to be coupled to the second input power source and controls the second switch to be coupled to the second input power source after the control unit effects a supply current flowing through a first power supply path and a second power supply path both coupled to the first input power source and the load to be reduced below a current threshold.

Abstract: The present disclosure provides a power system that includes a set of power devices and addressing lines. The set of power devices are electrically connected to a main power source, a standby power source and a server node. The addressing lines are electrically connected to the set of power devices, so that the set of power devices can correspond to a plurality of different addressing signals respectively. The set of power devices are switched at different times based on the different addressing signals, so that one of the main power source or the standby power source supplies power to the server node though the set of power devices.

Abstract: A power supply includes a transformer winding, a switching circuit, a controller and a filter circuit. The transformer winding is configured to provide a first voltage. The switching circuit is coupled to the transformer winding and includes a first and a second switching unit. On the condition that the power supply is operated under a standby mode, the controller controls the first and the second switching units to provide a discharging path between two terminals of the transformer winding. On the condition that the power supply is operated under an operating mode, the controller controls the switching circuit such that the switching circuit provides a second voltage according to the first voltage. The filter circuit is coupled to the switching circuit and configured to filter the second voltage to provide an output voltage.
