Patent number: 10720828Abstract: A power supply device includes a rectifying/smoothing circuit that receives an AC voltage input and converts the AC voltage into a DC voltage by rectification and smoothing, an AC voltage cut-off detection circuit that detects a cut-off of the AC voltage, and a voltage processing circuit that is connected to a post-stage of the rectifying/smoothing circuit wherein the post-stage means a downstream side from the rectifying/smoothing circuit and operates when the AC voltage cut-off detection circuit has detected a cut-off of the AC voltage. The AC voltage cut-off detection circuit is provided with a signal transmitting element that is connected to the post-stage of the rectifying/smoothing circuit, and receives power supplied from the rectifying/smoothing circuit and sends a signal to the voltage processing circuit when the AC voltage is cut off.Type: GrantFiled: February 20, 2019Date of Patent: July 21, 2020Assignee: Oki Data CorporationInventors: Tomoyuki Kojima, Hideki Shinyama
