This paper proposes a new solar power generation system, which is composed of a DC/DC power converter and a new seven-level inverter. The DC/DC power converter integrates a DC-DC boost converter and a transformer to convert the output voltage of the solar cell array into two independent voltage sources with multiple relationships. This new seven-level inverter is configured using a capacitor se...

Grid connected inverters are important building blocks in renewable energy conversion systems. In conventional voltage sourcing grid connected inverters, any mismatch between the synthesized output waveforms of the inverters and the grid voltage will generate large erroneous currents unless a fast current feedback is used. The current control requires rather fast sampling rates and considerable...

This paper presents a machine learning technique for fault diagnostics in induction motor drives. A normal model and an extensive range of faulted models for the inverter-motor combination were developed and implemented using a generic commercial simulation tool to generate voltages and current signals at a broad range of operating points selected by a machine learning algorithm. A structured n...

The 4-leg inverter can adjust the load current or output voltage even under unbalanced conditions, but it is known that additional switch arm to 3-leg increase overall cost and failure rate. This paper aims analyze rate mean time between failures (MTBF) of inverters using part count analysis (PCA) fault-tree (FTA), compare price inverters. FTA rate, including type, number connection status circ...

In modern industrial and power electronics applications, high-voltage high-current integrated modular transistors (IGBTs) are increasingly being utilized. The F-type inverter, which is a modified version of the T-type has emerged as promising option. This configuration separates common point bidirectional switch, reducing voltage stress resulting in lower inverter costs losses. simplified desig...

Switched-capacitor-based multilevel inverters for boost-type dc–ac power conversions usually exhibit a trade-off between the switch count and switch-voltage rating, i.e., reduction of one necessitating an increase other. Such dilemma is well addressed in this article by proposing novel single-phase nine-level inverter based on switched-capacitor network with single switch. The proposed then red...
