As promising and suitable candidates for high‐power applications, multilevel inverters have become one of the most promising solutions in various applications. However, power switching devices are highly subjected to thermal overheating, which leads to shortened lifetime and reduced reliability. Thermal overheating may result from the degradation of power switching devices due to continuous overloading...
This paper presents a unified space vector modulation (SVM) algorithm for lifetime prolongation of thermally-overheated power semiconductor devices in multilevel inverters. Thermal overheating is the main cause of shortened-lifetime and open-circuit faults of the devices. Power semiconductor devices are subjected to thermal overheating due to their ageing that results from continuous overloading and...
This paper introduces design and validation of space vector pulse width modulation (SVPWM) algorithm for reliability enhancement of multilevel inverters. Thermal overheating is the main cause of shortened-lifetime and open-circuit faults of power devices. It may result from ageing of semiconductor materials due to continuous operation and various operating conditions. Degradation and faults of cooling...
Boosting lifetime of power components in multilevel inverters is a major aim to enhance the total system reliability and performance. This paper presents a space vector pulse width modulation (SVPWM) strategy for lifetime prolongation of thermally-overloaded power devices in multilevel inverters. When a thermal overloading is detected in one of the power devices, the proposed algorithm is applied...
This paper investigates the design and validation of a new space vector pulse width modulation (SVPWM) algorithm for thermal protection of T-type three-level inverters. Thermal overheating is the main cause of shortened-lifetime and open-circuit faults of power devices. Power devices are subjected to thermal overheating due to degradation of power devices due to continuous overloading and power cycling,...
