Find the average load voltage of the rectifier circuit, if the device is switched to ON at α, angular angle.
1
\(\frac{{{V}_{rms}}}{\pi \sqrt{2}}\cos \alpha\)
2
\(\frac{{{V}_{rms}}}{\pi \sqrt{2}}(1+\cos \alpha )\)
3
\(\frac{{{V}_{rms}}}{\pi }\left( 1+\cos \alpha \right)\)
4
\(\frac{{{V}_{rms}}}{2\pi }\left( 1+\cos \alpha \right)\)
