Title:
CONTROL METHOD OF INVERTER
Document Type and Number:
Japanese Patent JPS5534837
Kind Code:
A
Abstract:
PURPOSE:To provide three-phase three-wire output terminals without producing higher harmonic of magnification of three with star connection of the secondary windings of transformer. CONSTITUTION:The secondary windings of transformers TRR, TRS, TRT are connected by a star system. This allows the secondary terminals between R-S, S-T, R-T, namely three-phase three-wire output to produce no higher harmonic of magnification of three, namely, tertiary, square tertiary, quindenary higher harmonic waves.
