Abstract: A distributed power supply circuit supplying common power to multiple packages in an apparatus so that a primary voltage of the common power is converted into a secondary voltage in a voltage conversion part so as to be supplied to a circuit in each of the packages is disclosed. The distributed power supply circuit includes a power supply monitoring part configured to monitor the primary voltage; a reset part configured to stop the supply of the primary voltage to the voltage conversion part when the power supply monitoring part detects the abnormality of the primary voltage; and a discharge part configured to release a stored charge on the primary side of the voltage conversion part when the power supply monitoring part detects the abnormality of the primary voltage. The power supply monitoring part is separated from the reset part by multiple diodes so as to be provided in parallel with the reset part.
