A Bi-processor architecture for a high performance P.W.M. modulator

A new low-cost architecture For a P.W.M. modulator is presented. It uses two microprocessors in parallel and is adapted to any kind of voltage inverter, thanks to a programmable preconfiguration. It achieves high performance, increased reliability and ease of use. The use of an optimized P.W.M. strategy avoids any current or flux transient.
