Elevator Control Using Dedicated Processor for Power Electronics (PP7)

Currently, elevator drive units, from medium-low-speed elevators to high-speed elevators, generally adopt inverter control. Technological advances have promoted steady progress year by year with these units. We have developed a highly functional processor dedicated to power electronics (PP7) in which a 32-bit-CPU and multi-function digital circuit are integrated on to a single chip. This report outlines this dedicated processor and describes its application to a high-speed elevator drive system.
