PURPOSE:To easily obtain an AC current having no higher harmonic ingradient by composing in different combinations of the output of multiple inverters using a transformer. CONSTITUTION:Signals are supplied from a phase-dividing circuit to inverters 5-1-5-8, which are consisted of single-phase inverters capable to output an AC power having a phase difference of 22.5 deg. one another and their output is supplied to the primary windings 6-1a-6-8a of the corresponding transformers 6-1-6-8 respectively. The transformers 6-1-6-8 have primary windings 6-1a-6-8a, secondary windings 6-1b-6-8b and tertiary windings 6-2c-6-8c. The secondary windings 6-1b-6-8b (excluding 6-5b) are connected in series one another and the tertiary widings 6-2c-6-8c are also connected in series in the same way. |
