PARALLEL OPERATION DEVICE FOR INVERTER

摘要

PROBLEM TO BE SOLVED: To make load sharing selectable in the case of executing parallel operation. SOLUTION: A table correlating to effective power and a frequency is selected so as to perform control lowering the frequency of an AC output at the time as the effective power large increases, the effective power is detected in a microcomputer 61, and the control is performed so as to execute operation under the desired frequency.
