  • Patent number: 10778109
    Abstract: A power supply includes a primary circuit connected to a primary winding of a transformer and a secondary circuit connected to a secondary winding of the transformer. The primary circuit includes MOSFETs, and the secondary circuit includes MOSFETs configured to rectify power transmitted from a primary side of the transformer and includes a capacitor configured to store the rectified power. The secondary circuit performs a discharge operation of discharging the capacitor and causing a current to flow into the secondary winding of the transformer to reduce a source-drain voltage of the MOSFETs before the MOSFETs are switched from an off state to an on state. Thus, the power supply having a high power-conversion efficiency even during low output is provided.

  • Publication number: 20200235677
    Abstract: A power supply device is provided with an output unit, an input unit, a rectifier circuit, a switching circuit, and a controller. The input unit inputs an AC input. The rectifier circuit has a smoothing capacitor and converts the AC input into a rectified output. The switching circuit switches between an ON-state in which input impedance is low and an OFF-state in which input impedance is higher than that in the ON-state. The controller sets a modulation ratio such that, when controlling the switching circuit to switch between the ON-state and the OFF-state, at least a portion of a period, in which the modulation width of the modulation duty ratio becomes maximum, is included in a period from a time when an input current inputted to the smoothing capacitor is generated to a time when the voltage of the smoothing capacitor reaches a maximum value.
