This paper investigates the fault-tolerant capacity of a modified three-level Active Neutral Point Clamped (ANPC) inverter when its switches are submitted to open and short-circuit failures. The main change consists on adding a thyristor in parallel with each inverter switch. This improves the behavior of the converter when a switch fails. Fault detection and identification methods are presented together...
The monitoring of power converters is critical for obtaining systems with self-diagnostic capabilities and fault-tolerant features. This paper presents an analytical work concerning the operation of matrix converters (MCs) under the presence of open-circuit faults and discusses the applicability of a method for the diagnosis of this type of failures. The proposed method uses the absolute values of...
This paper presents a survey on existing methods for fault diagnosis and protection of IGBT's, with special focus on those used in three-phase power inverters. Twenty one methods for open-circuit faults and ten methods for short-circuit faults are evaluated and summarized, based on their performance and implementation efforts. The gate-misfiring faults and their diagnostic methods are also briefly...
Fault diagnostics of power converters have drawn increasing attentions due to the widespread adoption of advanced power control devices, such as motor drives and uninterruptible power supplies. This paper presents a literature survey on existing methods for fault diagnosis and protection of IGBTpsilas, with special focus on those used in three-phase power inverters. Eleven methods for open-circuit...
