A transformer includes a magnetic core set and 2N pairs of windings. The magnetic core set includes a first magnetic core, a second magnetic core, a first magnetic column, and a second magnetic column. Each of the pairs of windings includes a high-voltage side winding and a low-voltage side winding. Each of the pairs of the windings surrounds one of the first and the second magnetic columns. The surrounding direction of the high-voltage side windings surrounding the first magnetic core is opposite to the surrounding direction of the high-voltage side windings surrounding the second magnetic core.

Transformer

A planar winding transformer includes a magnetic core set and a multilayer circuit board. The magnetic core set includes two magnetic cores and two magnetic columns. The two magnetic cores are parallel to each other. The multilayer circuit board is disposed between two magnetic cores, and two magnetic columns penetrate through the multilayer circuit board. The multilayer circuit board includes two low voltage winding layers and one high voltage winding layer. Two low voltage winding layers are connected to each other in parallel, and the high voltage winding layer is disposed between two low voltage winding layers. When the high voltage winding layer receives a polarity current, at least one of the low voltage winding layers generates a corresponding induced current. Two magnetic cores and two magnetic columns form a closed path for magnetic flux.

An intelligent stable power supply system includes a first power input module, a first non-return valve module, an active pulse wave generation unit, a DC power processing unit, and a control unit. When the control unit determines that a first voltage value is less than a first predetermined value or greater than a second predetermined value, and a second voltage value is between the first predetermined value and the second predetermined value, the control unit firstly controls the first non-return valve module being from an on state to an off state, and then controls the second non-return valve module being from an off state to an on state so that a power signal of the second power input module flows into the active pulse wave generation unit and the DC power processing unit to output a DC power signal.

A power supply device, a power supply management module and method are provided. The power supply device includes a power supply management module. The power supply management module includes a first and a second power supply module, a detection unit, and a switching control module. The first power supply module includes a first alternating current input end, a first rectifier circuit, and a first switch unit. A first end of the first switch unit is connected to the first rectifier circuit. The second power supply module includes a second alternating current input end, a second rectifier circuit, and a second switch unit. A third end and a fourth end of the second switch unit are connected to the second rectifier circuit and a second end of the first switch unit, respectively. The switching control module controls the first and the second switch unit according to a detection signal.

A power conversion system includes a first and a second energy storage element, a first boost circuit, a switching element, a control circuit and a detection circuit. The first boost circuit is coupled between the first and the second energy storage element. The switching element is coupled to the first boost circuit in parallel. When the first voltage value is lower than a first preset level, the control circuit turns off the switching element and drives the first booster circuit to maintain a second voltage value according to the first voltage value, so that the power conversion system operates in a first state. When the first voltage value is equal to or larger than the first preset level, the control circuit turns on the switching element and turns off the first boost circuit, so that the power conversion system operates in a second state.
