摘要
Multi-Port Magnetic Network Energy Routers (MNER) is a potential topology due to its performance in quick dynamic response, centralize control and improvement of system efficiency. However, the impact of some factors causes parameter mismatch that the performance of model-based control strategies is deteriorated. Although parameter identification is a solution providing precise parameters, it brings extra stress to the compute units. In this paper, a feedback control strategy is proposed that the error of phase-shift is fixed according to the difference between output power and reference power. The proposed strategy is robust to parameter mismatch of inductance itself. Performance of the proposed strategy is analyzed theoretically and the results of simulation verify the effect of this strategy.
