  • Heating device and image formation device
    Patent number: 10635031
    Abstract: A heating device includes: a power unit as a primary device which supplies an alternating-current output voltage; and a secondary device including a heater which generates heat by using the alternating-current output voltage. The power unit includes: a rectifier which rectifies an alternating-current input voltage; an inverter which converts a direct-current voltage generated from an output of the rectifier to the alternating-current output voltage; a first detector which detects the alternating-current input voltage; a second detector which detects the alternating-current output voltage; and an inverter controller which receives information indicating a set voltage of an output of the inverter, and controls the inverter such that the alternating-current output voltage approaches the set voltage based on a first detection value outputted from the first detector and on a second detection value outputted from the second detector.
