A Step-by-Step Multi-Stage Filter Design Method of an Active Three-Phase Three-Level Rectifier for Aircraft Application

The design of passive filters for rectifier topologies in modern aircraft is complicated by the variable frequency power supply and stringent regulatory requirements. This paper introduces a straightforward design approach that bypasses complex optimization algorithms, aiming to enhance power density. The referred method is applied to develop a passive, multi-stage filter for a bidirectional three-phase, three-level rectifier system.
