A subsea boosting module (106, 206, 306, 406, 506, 606, 706) for use with a direct current (DC) power system includes a housing (108) defining at least one interior chamber (228, 230, 232). A fluid pump (112) is disposed within the interior chamber (228, 230, 232). An electric motor (114) is disposed within the interior chamber (228, 230, 232) and drivingly coupled to the fluid pump (112). A plurality of power components (116) is disposed within the interior chamber (228, 230, 232) to deliver power to the electric motor (114).
