“…are disregarded, as it is considered that the converter hardware and control are robust enough to avoid such events. According to literature, [19][20][21] IGBT failures from fatigue lead to switch open-circuit fault. Thus, it is considered that IGBTs will only fail in open-circuit mode.…”

The increasing solar photovoltaic (PV) generation highlights the importance of PV systems’ scalability, reliability, and cost reduction. Herein, a modular fault‐tolerant PV multistring inverter to address this challenge is proposed. The proposed inverter features a modular dc‐dc conversion stage and a dc–ac conversion stage. This configuration allows scaling the inverter power rating by simply increasing the number of PV strings, associated dc‐dc modules, and dc–ac‐stage heatsink size and output‐filter inductances’ current rating. The fault‐tolerant capability allows for tolerating a first‐switch open‐circuit fault on either stage and continuing operation. This property allows increasing by half the inverter lifetime compared with nonfault‐tolerant solutions (dismissing inverter reparation and degraded mode of operation), with a low impact on the cost increase (3–7%) and an efficiency reduction after a fault occurs of only 0.33–1%, depending on the module count and fault localization. A generalized reliability assessment demonstrates that lifetime increase is achieved regardless of the number of modules. Additionally, it allows reducing the operation and maintenance costs and revenue losses due to unscheduled system shutdowns. To validate the proposed inverter, a lab–scale prototype with two modules is tested under emulated faults, validating the feasibility of the proposed inverter.

“…In [45], it is stated that thermal stresses, mechanical vibrations and humidity are the first three causes of inverter failures caused by long-term wear-out. Inverter manufacturer's test conditions in the production phase may not match the field operation.…”

Automated guided vehicles have been part of all production and logistic systems. Industry 4.0 technologies have also increased the applications of AGVs because of the demand for autonomous operations with minimum human power. In parallel to the growth of AGV market, researchers and application engineers need a holistic approach considering all aspects of development and application of AGVs.Objective of this study is to provide guidelines for AGV development with focus on traction systems. Traction topologies, motor and inverter specifications, energy efficiency solutions, failure risks of AGV motors, and electrical system development issues are reviewed.
