India experiences a wide gorge between its electrical power demand and supply due to various factors like insufficient capacity, powers losses etc. Owing to this India serves as a perfect model to implement distributed generation wherein energy sources are located close to the end users by creating a microgrid with various sources feeding to the loads connected on the grid. A microgrid based on photovoltaic...
Reduced Voltage Source Multicell Converters are one of the best alternative for Capacitor Multicell Converter, as the former uses only a single voltage source as compared to the later which uses two voltage sources for a single phase converter. In this paper three different levels (i.e., 5 level, 7 level and 9 level) of reduced voltage source multicell converters are analyzed by taking THD as an analyzing...

This paper discusses about unit template based AC current control using two methods: phase information from phase locked loop(PLL) and voltage peak estimation method. Since the behavior of the synchronous reference frame PLL(SRF-PLL) varies owing to the PI gains constrained to harmonic rejection bandwidth leads to a sluggish response. On the other hand an unit template voltage based hysteresis current...
