摘要
An apparatus for space vector modulation of a multi-level inverter, the apparatus comprising: a triangle generator for finding a modulation triangle enclosing a reference voltage vector, the modulation triangle comprising vertex vectors; a duty ratio calculator for determining duty ratios for the vertex vectors; a switching function selector for selecting switching functions corresponding to the vertex vectors; a forbidden transition identifier for identifying a forbidden transition between two of the vertex vectors; and a control module for applying the switching functions to the multi-level inverter according to the duty ratios and avoiding the forbidden transition.
