Abstract
A method of controlling a multilevel inverter of NPC (Neutral Point Clamped) type. The method includes regulating the electrical potential of the mid-point when the inverter operates at full voltage, that is to say in overmodulation. In this case, the method firstly determines the position of the control voltage vector in one of the six identical triangles covering the hexagonal vector space and thereafter decomposes the control voltage vector in the triangle by taking account of control combinations, defined in this triangle, for the switching arms.
