|20130278056||DC Power Supply System and Control Method - A DC power supply system and a control method, which can continue charging of a storage battery with a constant current even if an assist current is needed due to, for example, overload during charging of the storage battery and can suppress a current output from the storage battery as much as possible. In a power supply system, when a charger operates at a potential of an output voltage smaller than the potential of the output voltage of a rectifier during charging of the storage battery, the output current of the charger is controlled so that a charging current Ie supplied from the charger to the storage battery is kept at a predetermined value, and when a load requires a current larger than the current supplied by the rectifier during charging of the storage battery, the potential of the output voltage of the rectifier is reduced smaller than the potential of the output voltage of the charger by a current drooping operation, and the diode is electrically connected, the output current of the charger is controlled so that the charger outputs the assistant current Ic supplied toward the load while the charging current Ie is kept at a predetermined value.||10-24-2013|
