Implementation of a space vector modulation for an advanced ANPC three level inverter

In this paper an implementation of a modified three level space vector modulation on a microcontroller with a floating point unit is described. The space vector diagram is grouped to avoid commutations between both zero states and skipping of states which results in high inductive commutations. The...

Summary:In this paper an implementation of a modified three level space vector modulation on a microcontroller with a floating point unit is described. The space vector diagram is grouped to avoid commutations between both zero states and skipping of states which results in high inductive commutations. The calculation time for the space vector modulation is evaluated, therefore the execution time for different operations and functions is measured and compared with the times needed without any optimisations or floating point unit. Moreover a split of the source code is shown to simulate the inverter function with the help of Matlab/Simulink.
