“…As control for complex power electronic circuits became more demanding, programmable digital signal processors (DSPs) enjoyed wide adoption in various fields [9]- [12]. In contrast to common microcontrollers, DSPs are application specific ICs that usually have Harvard architecture, hard-wired logic, 16 or 32 bit word length, leading to high computation capability.…”

This paper presents a multi-processor control system for a general purpose five-level cascaded inverter for real time power system applications. Practical design considerations for the digital controller architecture as well as the power converter are discussed and a 3 kVA laboratory prototype is presented. As a case study, A StatCom with battery energy storage was implemented on this multi-processor controlled inverter system. To eliminate the troublesome PI parameter tuning and the limitation of small signal models, which exist in conventional control for StatComs, a new and simple control method based on large signal model was designed to realize four-quadrant power injections into a grid. Experimental results are provided to support the proposed concept.0-7803-8269-2/04/$17.00 (C) 2004 IEEE.
