FPGA Implementation of a General Space Vector Approach on a 6-Leg Voltage Source Inverter [PDF]

, 2011
A general algorithm of a Space Vector approach is implemented on a 6-leg VSI controlling a PM synchronous machine with three independent phases. In this last case, the necessity of controlling the zero-sequence current motivates the choice of a special ...
