    摘要: A high power factor rectifier circuit, provided with switching sections connected to an AC power supply for converting an AC voltage to a DC voltage, is formed with a bypass circuit provided. The bypass circuit, when the voltage of the AC power supply becomes higher than the voltage across a smoothing capacitor provided on the DC output side, makes a charge current flowing from the AC power supply to the capacitor bypass the switching section by making the switching section out of conduction. Thus, a rectifier circuit is provided which can be safely operated without causing any damage, or with minimized damage, even though an inrush current flows at turning-on the power or at recovery from a power interruption.

The power supply device has rectifier circuits that include a first circuit that rectifies a line voltage of the AC power supply, converting it into a direct current voltage of a first predetermined value, when the voltage of the AC power supply is a predetermined value or less, and a second circuit that rectifies a phase voltage of the AC power supply, converting it into a direct current voltage of a second predetermined value, when the voltage of the alternating current power supply exceeds the predetermined value. The first and second circuits operate in such a way that the AC input current is of the same phase as the voltage of the AC power supply.

    摘要: An entirely integrated EMI filter is based on a flexible multi-layer strip material. An EE or EI core comprises two side pillars and one middle pillar and forms a closed magnetic circuit. The middle pillar has an air gap. A first winding and a second winding respectively are wound around the two side pillars in a same winding direction. The middle pillar is wound with a third winding and a fourth winding, or with only a fifth winding. Passive components (e.g., all passive components) of the EMI filter are integrated into one core so that in its differential mode, insertion loss is significantly reduced, the size and volume are reduced, and the distribution constant of the EMI filter has less impact on the filter's performance.
