DG is nothing but a small scale generation unit connected directly to the distribution network or near customer load center. This system may or may not be connected to the electric grid. DG has a limited size of 10MW or less especially when DG is used in a distribution network. DG is installed at the place where it becomes impracticable to build a central(More)
Optimization techniques have become powerful tools in the design of power electronics converters. In this paper an optimization technique is proposed to design a multilevel converter. Unlike the majority of previous converter optimization, this technique considers multiple characteristics to be optimized. Efficiency, inductance, loss distribution and(More)
LLC resonant converters are widely used in distribution systems for energy conversion. Having a detailed simulation model of the power MOSFETs in an LLC resonant converter can significantly improve the dead time calculation and subsequently improve the DC-DC converter's efficiency. In this paper, a new model for power MOSFET employed in an LLC resonant(More)
