ABSTRACT:
A pulse-width-modulated inverter models the output response of the system for a given switching angle set under existent load and d.c. link conditions. Before implementation, a provisionally selected angle set is input to the model, which produces an output representative of system operation for the provisional selected set. The harmonics content of the model output is compared with criteria establishing maximally allowable amplitudes for the harmonics and the set is implemented only if the output meets the criteria.
