INVERTER APPARATUS AND APPLICATION THEREOF

WIPO Patent Application WO/2023/142538

A1

Disclosed in the present invention are an inverter apparatus and the application thereof. The inverter apparatus comprises an n-phase bridge inverter circuit (wherein n = 2k + 1, and k is an integer greater than or equal to 2) and n iron-cored winding coil combinations. The n-phase bridge inverter circuit is composed of n groups of unidirectional conductive electronic switch devices connected pairwise in series; and there is a definite electromagnetic induction relationship between iron-cored winding coils, so that a given direct-current power supply generates an n-phase alternating-current voltage source at n connection points of the n iron-cored winding coil combinations and n series connection points of the n groups of unidirectional conductive electronic switch devices connected pairwise in series, wherein the n-phase alternating-current voltage source refers to a group of n sine-wave voltage sources, which have equal amplitudes and have phases at intervals of 360°/n in sequence. In the present invention, a multiphase bridge inverting method is further used to generate a rotating magnetic field, thereby completely abandoning the working principle of a direct-current electric motor and realizing direct-current electric drive.
