Proposes novel multiple diode rectifier systems with asymmetrical multi-phase input ac voltages

This paper presents input impedance models for Multi-pulse rectifiers with series connected output that can be used for systemstability and dynamic power quality analysis. This model is based on linearization harmonics and makes use of Systematic mapping functionsthat describe voltage and current transfer through multi-phase diode rectifiers. Magnetizing inductance and line commutation due totransformer leakage inductance are also took into account. Numerical simulation for ۱۸-pulse rectifiers are presented for validation of theproposed model.
