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.
Clamp type transient suppressors are widely used to protect electronic equipment from damage during short periods of abnormal voltage on supply lines. However, the action of these suppressors, in conjunction with stray circuit elements, can induce secondary transient effects which may also disrupt equipment operation. This paper discusses the nature and origin of these secondary effects, and provides...
