Abstract

An evaluation function is proposed to solve the problem of midpoint potential imbalance in single-phase three-level pulse rectifier. Based on the model prediction algorithm, an evaluation factor is added to realize the midpoint potential balance of single-phase three-level pulsed rectifier without additional midpoint potential balance module. In order to reduce the cost of hardware design and improve the reliability of the circuit, the gridless pressure sensor algorithm is used. the traditional gridless pressure sensor has the problem of phase shift and amplitude attenuation due to the introduction of first-order low-pass filter. To solve the problem of phase shift and amplitude attenuation, an improved gridless pressure sensor algorithm is proposed, which uses the vertical relationship of α-β to compensate the amplitude and phase. The network-side AC voltage without phase shift and amplitude attenuation is obtained. The experimental results demonstrate the correctness and effectiveness of the proposed algorithm．
