发明名称 POWER SUPPLY UNIT
摘要 PROBLEM TO BE SOLVED: To provide a power supply unit which does not stop either one of a dispersed power source whose output rapidly drops and a dispersed power source whose transient response is slow even when both the dispersed power sources are connected in parallel to each other.SOLUTION: The power supply unit includes: a first dispersed power source with a first converter 4 which is connected with a solar battery 1, performs constant voltage control, and droops an output voltage when an input voltage is not more than a predetermined value, an input current is not less than a predetermined value or an output current is not less than a predetermined value; a second dispersed power source with a second converter 5 which is connected with a battery 2 other than a solar battery, connected in parallel to the first dispersed power source, performs constant voltage control, and droops an output voltage when an input voltage is not more than a predetermined value, an input current is not less than a predetermined value or an output current is not less than a predetermined value. The first converter controls an output voltage according to a voltage command, detects a decrease variation of an input voltage, and when the decrease variation of the input voltage exceeds the predetermined value, decreases a voltage command by the predetermined voltage.SELECTED DRAWING: Figure 1
