Cascaded Multi-level inverter for synchronization of power generated from PV system to utility grid is reported in this paper. Inverters are prone to several types of faults e.g. switch failure or dc link capacitor failure. Failure mode analysis of cascaded H-Bridge is widely discussed in the literature. Various methods for post-fault operation with reduced capacity (due to module failure) but with...
In this paper, Active and Reactive power management with the utility grid is achieved by integrating 7-level quasi Impedance Source Inverter (qZSI) with Thyristor based elements (Thyristor Switched Capacitor (TSC) and Thyristor Switched Reactor (TSR)). Major portion of the reactive power is managed by the thyristor based elements and the remaining reactive power is managed by the cascaded qZSI. The...
