Steady State and Transient Analysis of 6-Pulse Rectifier Bridges Including Faulty Diodes
Abstract: This paper addresses the steady-state and transient responses of un-controlled faulty 6-pulse diode rectifier bridge circuits. The faulty bridges can include several simultaneous diode valves’ open- or short-circuits. An efficient representation of the diodes is adopted in order to describe their performance in both the forward and reverse directions. A set of simultaneous differential and algebraic equations simulating the faulty rectifier bridge is presented. Its numerical solution is obtained through …

Study of Cascaded H Bridge Multilevel Inverter
Abstract: The inverters are now-a-days used broadly. Inverters are classified as two level inverters and multilevel inverters. There are too many limitations; conventional inverters at high power and high voltage applications. So, multilevel inverters become useful for high power and high voltage applications due to their increased number of levels at the output voltage. The harmonics are reduced by increasing the number of levels and output voltage has a tendency to-end-up …
