Tri-phase full-wave rectifier (Graetz bridge)

$V_A=A.\cos (2\pi .f.t)$

$V_B=A.\cos (2\pi .f.t-\frac{2\pi }{3})$

$V_C=A.\cos (2\pi .f.t-\frac{4\pi }{3})$

$V_{out}$: rectified signal with the following characteristics:

$\mathrm{F\; ripple}=6.f$

$V_{out}\max =\sqrt{3}.A$

$V_{out}\min =\frac{3}{2}.A$

$V_{out}\mathrm{mean}=\frac{3\sqrt{3}}{\mathrm{\pi }}.A$
