  • Publication number: 20230387827
    Abstract: A setting unit sets a duty ratio of a PWM signal based on a target voltage value, and outputs the duty ratio to a voltage conversion circuit. An estimated value calculation unit cyclically calculates an estimated duty ratio value based on the detected input voltage value and the detected output voltage value. An abnormality detection unit cyclically calculates, as a difference value, a difference between an updated estimated value and a comparison reference value, and detects abnormality of a voltage detection unit based on a change in calculated difference value. The updated estimated value is a newly calculated estimated duty ratio value. The comparison reference value is a value based on the estimated duty ratio value calculated in a cycle prior to a cycle in which the updated estimated value is calculated.

  • Publication number: 20230208300
    Abstract: A feedback control unit includes a controller which calculates a duty ratio for switching elements on the basis of a command value and a detection value of electrical information. A continuous/discontinuous current mode distinguishment unit includes a duty ratio increase/decrease distinguishment unit which performs distinguishment between increase and decrease in the duty ratio, and an output voltage detection value increase/decrease distinguishment unit which performs distinguishment between increase and decrease in a detection value of a voltage of second terminals. If the duty ratio has decreased and the detection value of the voltage has increased, or if the duty ratio has increased and the detection value of the voltage has decreased, the continuous/discontinuous current mode distinguishment unit determines that an operation mode is a discontinuous current mode, and feeds back a result of the determination to the feedback control unit.
