Steady-State Analysis of Modular Multi-Parallel Rectifiers (MMR) with Lossy Elements

Abstract

This paper presents a comprehensive steady-state analysis for active front-end Modular Multi-parallel Rectifiers (MMR) including parasitic elements. Generalised mathematical representations for the system’s gain and conduction loss effect are provided. In addition, the impact of the inductor losses and the firing angle on the system’s performance is investigated. A60kW Simulink model is utilised to validate the proposed mathematical model and the system characteristics and operating modes.
