The purpose of the present invention is a method for controlling a three-phase electrical machine (30) from an inverter (20). The method comprises the step of controlling a voltage at terminals of each phase (U, V, W) of the electrical machine (30) measured relative to neutrality with a value defined by a control vector associated with a subsector in which a control vector is located. Each sector of complex representation of a space vector modulation is subdivided into three subsectors which comprises: a central subsector centered on an active vector; a first lateral subsector associated with a first zero-sequence vector; and a second lateral subsector associated with a second zero-sequence vector and opposite the first lateral subsector relative to the central subsector.

    본 발명의 목적은 인버터(20)로부터 3 상 전기 기계(30)를 제어하는 방법이다. 공간 벡터 변조의 컴플렉스 표현으로 나타내는 각 섹터는 3 개의 서브섹터로 세분화되고, 이는 액티브 벡터 상에 중심을 둔 중심 서브섹터, 제 1 제로-시퀀스 벡터와 연관된 제 1 측면 서브섹터, 및 제 2 제로-시퀀스 벡터와 연관되며, 중심 서브섹터에 대해 제 1 측면 서브섹터 반대쪽에 있는 제 2 측면 서브섹터를 포함하고, 이는 중립에 대해 측정된, 전기 기계(30)의 각 위상(U, V, W)의 단자에서의 전압을, 제어 벡터가 위치하는 서브섹터와 연관된 제어 벡터에 의해 정의된 값으로, 제어하는 단계를 포함한다.
