Rectifed 3 Phase
Rectifed 3 Phase
(OP)
If you run a 3phase source through a fullwave bridge, what DC values of voltage and current would you get? Use 120 VAC, Delta as an example. I've been getting confused about the sqrt of 2 and 3.
Thanks
Thanks

Reference 1 Page 68 Figure 3.6 shows DC value of 3-phase voltage as
Ed=(3 x 3**0.5 x E1-n,m)/(PI)
which for 120V is:
Ed=(3 x 3**0.5 x 2**0.5 x 120)/3.14=280.7VDC

Using Mathcad, I came up with 162.2 Vrms.
