I´m a german design engineer and new on this Site. I need some hints and trends in designing controlling hardware for frequency inverters (3 Phase 400VAC) . My Boss demands a lowest cost solution. On the semiconductor market there are a lot of integrated components, like optocoupled Drivers or deadtime generators, which take over partially functions for motor control application, but those are expensive. The other choice is a cheaper discrete design of these functions. Ttherefore I have following question: Can you give further advantages or disadvantages to use these components.
