Design Optimization and Implementation of Genetic-Based Moving Sliding Manifold Strategy for Parallel Operation of DC-AC Converters

Abstract— In this paper, the optimal design to parallel operation of DC-AC converters using genetic-based moving sliding manifold strategy is proposed. The AC output voltage regulation and balanced current-sharing among the parallel modules are achieved by the use of the moving sliding manifold (MSS). However, while the load condition of the parallel-connected DC-AC converter is a large parameter variation, the chatter around the MSS occurs. The chatter may cause heat losses and high voltage harmonics in parallel-connected DC-AC converter output, and thus deteriorates system stability and reliability. To eliminate the chatter, the control gains of the MSS can be optimally adjusted by the use of the genetic algorithm (GA). With the proposed strategy, the parallel operation of the DC-AC converter yields a high-quality AC output voltage with low voltage harmonics and fast dynamic response even under large parameter variations, thus achieving more robust system. Experimental results are performed to demonstrate the proposed strategy.

Index Terms— Moving sliding manifold (MSS), chatter, genetic algorithm (GA), parallel operation, DC-AC converter.
