“…Another limitation of MIL-HDBK is that it does not have failure rate data for IGBT. It is suggested in [13] that BJT can be used to model failure rate of IGBT. For determining failure rate of IGBT some researchers have also suggested a factor of 0.5 of MOSFET base failure rate [14], [15].…”

To improve the reliability and efficiency of grid tied inverters, it is suggested to replace some of the fully controllable devices by semi-controllable devices like thyristor. A modification for the HERIC topology is proposed, wherein the upper two switches of inverter leg and additional series connected switches for freewheeling are replaced by thyristors.The efficiency and reliability of full bridge transformerless inverter, full bridge transformer based inverter, HERIC transformer-less inverter and proposed transformer based inverter are calculated. It is shown that the proposed change not only improves reliability but also the efficiency. Calculated efficiency is around 98% and calculated failure rate of inverter stage is 4150 FIT (Failures In Time = 10 −9 failures per hour). These figures are better than those reported for the other popular topologies. Simulation results of the grid tied inverter feeding power at unity power factor are given.

“…Most of the recent research into reliability of BESS has concentrated only on the reliability of the power electronic components and the power converter reliability, where the reduction of semiconductor switches and component optimisation were the key to improve reliability [2][3][4][5][6]. The power electronic switches were identified as the weakest link in the power circuit.…”

This paper is part of a project which aims to research the opportunities for the re-use of batteries after their primary use in low and ultra low carbon vehicles on the electricity grid system. One potential revenue stream is to provide primary/secondary/high frequency response to National Grid through market mechanisms via DNO's or Energy service providers. Some commercial battery energy storage systems (BESS) already exist on the grid system, but these tend to use costly new or high performance batteries.Second life batteries should be available at lower cost than new batteries but reliability becomes an important issue as individual batteries may suffer from degraded performance or failure. Therefore converter topology design could be used to influence the overall system reliability. A detailed reliability calculation of different single phase battery-to-grid converter interfacing schemes is presented. A suitable converter topology for robust and reliable BESS is recommended.

“…In most cost-driven applications, a single component failure immediately results in a defective product. To ensure sufficient reliability, power semiconductors are not used up to their full potential [16]. A basic circuit that is applied in most power converter topologies is the commutation cell [17], which consists of two switches, one inductor and one capacitor.…”

Abstract-The extended commutation cell is a 4-port, 4-switch cell that allows for bidirectional energy transport in two orthogonal directions throughout the cell. By cascading multiple cells a multilevel converter can be constructed with a high number of cells. The voltage across each cell capacitor can be adjusted independently of the load, resulting in high flexibility in output levels. In this paper the general theoretical analysis for this cell, including the necessary design tools is detailed. Experimental results of a 2-cell 8-level dc-ac converter are given. The outcomes are in good agreement with the analysis and simulation results.
