In order to remove undesirable lower harmonics from a cascaded H-bridge multilevel inverter and solve constrained in design optimization issue with parameters involved changeable objective function for the given system, TLBO approach is provided. To test stability of recommended system output was designed be supplied various load drive systems. The entire efficiency wind grid inverters has now ...

The fabrication of components involves the deposition multiple beads in layers for wire-arc additive manufacturing (WAAM). WAAM performed using gas metal arc welding (GMAW) allows parts through multiple-bead multi-layer deposition, which depends on process variables. Thus, selection parameters along with their required levels is mandatory to deposit WAAM. To obtain desired parameters, bead-on-p...

A comparative study is performed to design an optimal PID controller for automatic voltage regulator system using different optimization techniques. The presented approaches are referred as particle swarm (PSO) algorithm, cuckoo search (CSO) moth flame (MFO) water cycle (WCO) teaching–learning-based (TLBO) and hill climbing (HCO) algorithm. Transient response parameters, which rise time Tr, set...

The information of the fault frequency characteristics is great importance for all associated diag nostics. This requires a high-resolution spectrum analysis to achieve efficient monitoring machinery faults, especially while diagnosing rotor bar breakage under light load conditions, because frequencies almost overlap with fundamental. In this context, rather than looking several bands are obser...
