Due to the single phase characteristic of individual arms Modular Multilevel Converter (MMC) topology, difference between instantaneous AC and DC side power must be buffered in module capacitors. This results large capacitors compromising density cost MMC. In this paper, a multi-objective optimization scheme is formulated that aims at reducing required capacitance semiconductor losses same time...

In the main this paper introduces the concept of chromatic harmonic polynomials denoted, $H^chi(G,x)$ and chromatic harmonic indices denoted, $H^chi(G)$ of a graph $G$. The new concept is then applied to finding explicit formula for the minimum (maximum) chromatic harmonic polynomials and the minimum (maximum) chromatic harmonic index of certain graphs. It is also applied to split graphs and ce...

In this work, an electronically tunable large range phase shifter based on a broadband Injection-Locked Third Harmonic SelfOscillating Mixer (IL3HSOM) is designed and analyzed. This multifunctional circuit generates a down-converted Intermediate Frequency (IF) signal and provides a theoretical 540◦ continuous phase shift range. The conversion gain and the bandwidth of the circuit are optimized ...

Particle and electrode surfaces were altered to examine the effects on the electrorheological response of barium titanate/silicone oil suspensions. Unmodified suspensions exhibited nonlinear conduction. The dynamic yield stresses scaled as E, where n < 2 at all electric field frequencies, and the current had substantial harmonic content, a hallmark of nonlinear conduction. Modifying the particl...
