Question

The voltage across a switch and current through a switch is shown in the figure. The power loss during turn on transition is _________ kW.

Answer 1

$P=\frac{1}{T}{\int }_0^{T}V\left(t\right)i\left(t\right)dt$

$=\frac{1}{1\times {10}^{-6}}[(\frac{1}{2}\times b\times h)\times 300+(\frac{1}{2}\times b\times h)\times 50]$

$=\frac{1}{1\times {10}^{-6}}[(\frac{1}{2}\times 0.5\times {10}^{-6}\times 75)\times 300+(\frac{1}{2}\times 0.5\times {10}^{-6}\times 300)\times 50]$

$=9.375kW$
