  • Patent number: 10594220
    Abstract: A chopper section of a power supply device includes a plurality of step-down chopper circuits, and multiphase control of the step-down chopper circuits is performed using gate signals having phases displaced from each other. This shortens the period with which output signals of the step-down chopper circuits are changed. Shortening the period reduces the amount of jitter resulting from a gap between the occurrence of a command signal and a sampling point that is a point in time at which a gate signal is generated. The number of phases of the gate signals equals the number of phases of the step-down chopper circuits. The control of the gate signal generator is asynchronous to feedback control by the controller. Points in time (sampling points) at which gate signals are generated are points in time of generation (sampling points) after a point in time at which the controller calculates a manipulated value.
