摘要: Based on singular perturbation theory and matrix eigenvalue theorem, an order reduction principle of neglecting fast dynamics fixing slow is proposed for multi-time scale systems. The can ensure steady state stability consistency between original reduced system. To validate this principle, the switch cycle average models typical converters are made, a simple AC/DC hybrid power system built. Finally, test by simulation results demonstrate effective applicable analysis
