摘要: The three-level neutral point clamped (3LNPC) inverter has the problem of unbalanced power loss and temperature. This paper proposes a temperature balance method based on finite control set modulation model predictive (FCS$-\mathrm{M}^{2}$ PC). Firstly, periodic current switch is measured delay compensation made to predict next switching cycle. Then, evaluation function value calculated find optimal state sequence time. output signal that instructs move in at corresponding After complete, prediction cycle begins. can be used low medium frequency systems, it does not need make every sampling period, which saves computation. simulation results show effectiveness proposed method.
