While impressive progress has been already achieved in wide-bandgap (WBG) semiconductors such as 4H-SiC and GaN technologies, the lack of intelligent methodologies to control gate drivers prevented exploitation maximum potential semiconductor chips from obtaining desired device operations. Thus, a potent ongoing trend is design fast driver switching scheme upgrade performance electronic equipme...
Power semiconductor devices are key to delivering high-efficiency energy conversion in power electronics systems, which is critical efforts reduce loss, cut carbon dioxide emissions and create more sustainable technology. Although the use of wide or ultrawide-bandgap materials will be required develop improved devices, multidimensional architectures can also improve performance, regardless unde...
The loss of balanced voltages involves a voltage drop due to symmetric three-phase errors, or the initiation of high-power three-phase loads or symmetric three-phase switches. While these events in an unbalanced way lead to asymmetric voltage drops. Voltage drops can cause asymmetric load on the power grid, the occurrence of volatility, and even network power outage. One of the most common ways...
The development of power electronics technology is driven by the insatiate demand to control electrical power. The new power electronics devices reduce the volume of the converters by three to four orders of magnitude compared to their mercury arc predecessor. And the turn-on and turn-o0 time has decreased from milliseconds to the microseconds and even nanoseconds, depending on power level. The...
Power electronics is rich in nonlinear dynamics. Its operation is characterized by cyclic switching of circuit topologies, which gives rise to a variety of nonlinear behavior. This chapter provides an overview of the chaotic dynamics and bifurcation scenarios observed in power electronics circuits, emphasizing the salient features of the circuit operation and the modelling strategies. This chap...
Out of many renewable energy resources, solar energy is one of the conspicuous sources of energy which can supply the increasing demand of energy. As of May 2014, India has an installed PV capacity of 2.5 GW. The solar photovoltaic project includes power electronics with high quality performance devices, incorporated with smart energy management principles. Power electronics is used to improve ...
