Draw an equivalent circuit to represent such rectifier -

Question

A single-phase diode bridge is supplied by an a_c source of 257 V, 60 Hz. This bridge in turn supplies a dc load of I_dc= 60 A.

Estimate the voltage drops due to (1) source with an inductance of 0.02 m_H, (2) each diode with forward voltage drop of Δ_Vf = 0.6 + 0.0015 I_dc, and (3) source and wiring resistances of R_r = 0.0015 Ω.

Draw an equivalent circuit to represent such rectifier. 

Research the circuit topologies for implementing HVDC in order to connect multiple offshore wind turbines or multiple tidal generators to the grid with an underwater cable.
