An electric power generating system (EPGS) (100, 200, 300) includes a generator (102, 202, 302) configured to power a direct current (DC) load (109A, 209A, 309A) via a power distribution module (107, 207, 307). The power distribution module (107, 207, 307) includes a solid state power converter (SSPC) (108A, 208A, 308A). A decoupling filter (106, 206, 306) connected between the generator (102, 202, 302) and the power distribution module (107, 207, 307), and includes an inductor connected in parallel with a resistor and a solid state switch, the resistor and solid state switch being connected in series. During current limiting conditions in the SSPC (108A, 208A, 308A), the solid state switch of the decoupling filter (106, 206, 306) is configured to be open, and during the absence of current limiting conditions in the SSPC (108A, 208A, 308A), the solid state switch of the decoupling filter (106, 206, 306) is configured to be closed.
