# How can you work out the internal resistance of a rectified 3 phase generator?

If there is a star topology 3 phase generator such as this-

Connected to a full-wave diode rectifier such as this-

Can you approximate the circuit to this-? (assuming steady state, DC load)

If so, how could you calculate R_G?

How would R_G relate to the resistance measured when you place a multimeter between the generator pins R, B, Y ? (e.g. resistance between R and B, resistance between B and Y etc.)

Images references-

• R_G = approx. the same as R_RB or R_BY or R_RY + 2*R_diode. – Marko Buršič Aug 13 '19 at 11:07
