A common mode inductor apparatus includes a magnetic core, a first coil winding and a second coil winding. The magnetic core has a first winding zone and a second winding zone. The first coil winding is wound in three winding areas within the first winding zone, wherein two neighboring winding areas within the first winding zone are separated by a gap. The second coil winding is wound in three winding areas within the second winding zone, wherein two neighboring winding areas within the second winding zone are separated by a gap.

Common mode inductor apparatus having coil winding wound in multiple winding areas, and related winding method of common mode inductor apparatus and electromagnetic interference filter circuit

The present invention discloses an electromagnetic shielding assembly including an electromagnetic interference shielding component including a plate body and a bending portion. An included angle is formed between the plate body and the bending portion, and the plate body and the bending portion cover an input socket of a power supply. The electromagnetic interference shielding component includes at least one grounding pin disposed on the plate body or/and the bending portion and configured to ground with and screw to a housing of the power supply, and a welding pin disposed on a side of the bending portion away from the plate body and electrically connected to an auxiliary circuit board. The electromagnetic interference shielding component provides functions of EMI shielding, lightning (current) discharging and fixture, which can simplify the structure, increase the discharging speed and time, and reduce the amount of disturbance of the large current instantaneous to the ground.

Electromagnetic shielding assembly, electromagnetic interference and lightning protection module and power supply

The invention discloses a circuit board output structure, which includes a power output section disposed on a circuit board and at least one metal connection stand electrically connected to the power output section. Each metal connection stand includes a first connection piece showing an included angle with respect to the circuit board. A plurality of connection holes for electrically connecting output wires are formed on the first connection piece. When it is required to change an output specification, the replacement can be more simple and convenient since the metal connection stand may be directly replaced without replacing the whole circuit board. Because the first connection piece has the included angle specified with respect to the circuit board, R angle and stress of the inserted output wires may be reduced to prevent the output wires from damage, detaching from the circuit board or having poor electrical contact after the assembly.

Power supply and circuit board output structure thereof

A power supply system includes a power conversion circuit, a conversion control circuit, an auxiliary power module, an electricity supply module and a power supply control circuit. The power conversion circuit converts an input power into an output power used as an output of the power supply system. The conversion control circuit is arranged for controlling an operation of the power conversion circuit according to a control power. The auxiliary power module is arranged for selectively outputting a first electrical power to the conversion control circuit. The electricity supply module is arranged for providing a second electrical power. The power supply control circuit is coupled to the auxiliary power module and the electricity supply module, and arranged for referring to at least the second electrical power to determine whether to provide the first electrical power or the second electrical power as the control power for the conversion control circuit.
