Development of Cascade H Bridge SVG
2021 IEEE 16th Conference on Industrial Electronics and Applications (ICIEA), 2021Recent years have witnessed a rapid development of Electrified railway. A large amount of reactive power can be generated when the electric locomotive is too much on the traction network, It Cause a serious decline in power quality, Harmonics and reactive power has negative impacts on stability and security of locomotive running.

Modelling H-Volatility with Fractional Brownian Bridge
2022We express the realized volatility in terms of the Hurst exponent of the trajectory drawn by the market index. By analyzing distribution, stationarity, and (partial) sample autocorrelation of the estimated paths, and exploiting the empirical law of return to the central value 1/2, we model the dynamics of H(t) (and hence of the volatility) through a ...

Interleaved multicell semi-bridge rectifiers for cascaded H-bridge multilevel converters
Proceedings of The 7th International Power Electronics and Motion Control Conference, 2012This paper introduces a new approach to generate the dc-link voltages for a cascaded H-bridge inverter using interleaved single-phase multicell semi-bridge rectifiers. Compared to previous approaches, the presented solution improves input current low-order harmonic performance, reduces input current switching harmonics, and achieves higher overall ...

Cascaded H-Bridge Multilevel Active Compensator
2006 IEEE International Power Electronics Congress, 2006A compensator for harmonics and reactive power is presented based on a Cascaded H-bridge multilevel three phase inverter. Compensating current is calculated by using concepts of instantaneous power in a very simple way. The current regulation is carried out in a synchronous reference frame and the multilevel inverter is commanded by a sinusoidal ...

Video bridging based on H.261 standard
IEEE Transactions on Circuits and Systems for Video Technology, 1994Multi-point ISDN videoconferencing with video bridging in network-based servers represents a viable new network service. The paper presents a detailed technical analysis of a continuous presence video bridge using the H.261 video coding standard. The authors first compare the pros and cons of coded domain versus pel domain video bridges.

Control of H-bridge based multilevel converters
Industrial Electronics, 2002. ISIE 2002. Proceedings of the 2002 IEEE International Symposium on, 2002Multilevel converters are suitable for high voltage and high power applications. Among them H-bridge ones have encountered good success due to their simpler layout and the reduced number of components over the counterparts. H-bridge multilevel converters used as active rectifiers represent an attractive solution in traction systems due to the ...
