- 摘要:
- PROBLEM TO BE SOLVED: To prevent a parallel operation of two inverter generation units not to be conducted due to lack of balance between the two units when they are parallel-operated. SOLUTION: A DC power voltage VD obtained from a DC power source DC is detected and, when the DC power voltage VD exceeds a criterion that is set to be not less than a no-load output voltage, an output balance of the inverter generation units 1A, 1B is judged as being lost. When the imbalance is detected in the outputs of the both inverter generation units, an output voltage of the inverter generation unit 1B is reduced by allowing an overload operation of the inverter generation unit 1B, which carries a higher output voltage, to dissolve the imbalance of the outputs of the both inverter generation units.
