Multilevel inverters are capable of generating high-quality staircase pseudo sinusoidal voltage waveform with low total harmonic distortion. These types topologies may require large number switches and power supplies. This leads to higher cost volume the converter along complicated control algorithms. Recently, a branch multilevel converters is emerged as compact conversion units, in which their "reduced-structure" use lower active passive devices compared available topologies. Packed U-cell...

IoT refers to the internetworking of physical devices including passive sensors and actuators that collect, analyze exchange data via Internet. Recently, AMI has attracted attention praise from both industry commerce for vast improvements it brought about in accuracy online meter reading control. The modern Smart Meter can monitors electricity consumption, supply characteristics its environment (against tampering) sends stored back utility company load monitoring, trend analysis, network...
