Power electronic based inverters are the major components in industry. A fault diagnostics framework composed of a pattern recognition system, having machine learning technology as its integral part is utilized for failure detection of different switches and tracing multiple types of faults in an inverter. Hardware point of view power electronics inverter can be considered to be the weakest lin...

Induction heating (IH) technology is very popular in domestic applications because of its efficiency and safe operating properties. Resonant inverter circuits are widely used IH systems owing to their high soft-switching capability. Among the resonant inverters systems, single-switch quasi-resonant topology generally preferred for low-cost low-output-power applications. Despite advantage invert...

Multilevel inverters remain an area of research interest due to the superior performance against a two-level counterpart. Reducing switch count and stress on power electronic switches while maintaining sinusoidal stepped output remains challenge. A multilevel inverter topology has been proposed in this work which utilizes twelve four dc voltage sources produce 15-level staircase waveform. The o...

In this paper author discussed PI and fuzzy controllers with the three phase inverter concept and this converter connected to induction motor drive as load. This presents a unified control strategy that enables both islanded and grid-tied operations of three-phase inverter in distributed generation, with no need for switching between two corresponding controllers or critical islanding detection...

Semiconductor power modules are the key hardware components of a traction inverter. It drives motor speed and torque, managing energy exchange from battery to viceversa. The increasing demand for electric hybrid vehicle requests high performance modules. Power semiconductor devices based on wide band gap compound, like silicon carbide (SiC), have excellent electrical properties in terms on-stat...
