Microprocessor Based Converter Firing Pulse Generator

This paper discusses a microprocessor based converter pulse generator which is currently implemented in a commercially available high performance, inner current loop, adjustable frequency drive system. By incorporating intelligence in the form of the microprocessor, several performance and protection features have been included which would otherwise have been too costly. The general scheme of implementation is discussed including timing diagrams and flow charts. Advantages to this implementation approach are given with respect to conventional approaches not employing a microprocessor. Overall system implementation and response will also be discussed.
