Concepts

TL;DR

The matrix converter offers potential size and weight savings for aerospace applications. The study compares several rectifier‑inverter and matrix converter topologies for aerospace use and predicts their reliability. Reliability was predicted using MIL‑HDBK‑217F guidelines, noting that matrix converters, despite having more switches, experience lower voltage stress and thus lower failure rates. The reliability indicators of the different converter topologies are very similar.

Abstract

Several rectifier-inverter and matrix converter topologies suitable for aerospace applications are compared, and their reliability is predicted. The military handbook MIL-HDBK-217F guidelines have been used to predictreliability. The matrix converter has several attractive features for aerospace applications such as potential size and weight savings. Although the matrix converter has a higher number of semiconductor switches, they are subjected to a lower voltage stress, which decreases their failure rate. This results in the reliability indicators of the different converter topologies being very similar
