BY SUNEEL KUMAR M-TECH(POWER ELECTRONICS) Silicon carbide (SiC) unipolar devices have much higher breakdown voltages than silicon (Si) unipolar devices because of the ten times greater electric field strength of SiC compared with Si. 4HSiC unipolar devices have higher switching speeds due to the higher bulk mobility of 4H-SiC compared to other polytypes. In this paper‚ four commercially available SiC Schottky diodes with different

Landers Unforced Response 2 The state equation for an unforced dynamic system is Assume the solution is x ( t ) = e At x ( 0 ) The derivative of eAt with respect to time is d ( e At ) dt Checking the solution x ( t ) = Ax ( t ) = Ae At x ( t ) = Ax ( t ) ⇒ Ae At x ( 0 ) = Ae At x ( 0 ) Letting Φ(t) = eAt‚ the solution

Should the United States adopt the SI units/metric system or keep the American standard system? This is a question that has been arising since the invention of the metric system in France‚ 1790. Thomas Jefferson‚ president at the time of the invention‚ was deciding whether to adopt the system at the time in which he included on the constitution. I think that the metric system should be adopted in America‚ not only to please others‚ but to benefit us. The SI units are easier to use‚ would be more

Though one such 3D anode was demonstrated to offer 50% higher capacity‚ compared to its 2D counterpart‚ its ability to deliver much higher capacity‚ by geometrical modification‚ is presented. Furthermore‚ deposition of amorphous Si (a-Si) layer on the 3D electrode (a-Si/MWCNTs hybrid structure) offered enhancement in electrochemical response.
