Abstract

© The Institution of Engineering & Technology 2024.To reduce the computational burden of each interruption set aside to achieve parameter estimation of multiple power conversion architectures, this paper presented a decimation approach that can be employed to estimate coefficients of the transfer functions of multiple single-phase inverters in real-time operation. The simulation results show the effectiveness of the approach in terms of the same estimation accuracy and the same identification speed compared with the conventional way, however, the proposed approach only takes one-third of the computation burden suffered by its conventional counterpart per interruption.
