Title:
SYSTEM-LINKED INVERTER DEVICE
Document Type and Number:
Japanese Patent JP3862320
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a system-linked inverter device which realizes a stable operation of an inverter main circuit section by holding a loss due to a switching device low and thereby has a high power converting efficiency.
SOLUTION: This inverter device has a step-up circuit section 4 which steps up the input voltage that is input from a solar battery 1 that varies to a specified level by a step-up controlling circuit 10 and an inverter main circuit section 6 which converts the input from the step-up circuit section 4 to AC. In this case, the step-up controlling circuit 10 is so controlled that a difference between the output voltage V2 of the step-up circuit section 4 and a peak value of the voltage of a commercial power system may be constant by the output of a voltage detector which detects the supply voltage of the commercial power system 9.
