The system further comprises one or more power switching assemblies (29, 30, 31) to couple one of the DC bus sections to another of the DC bus sections and a system controller (28) controls the power sources and the power switching assemblies. An inverter (32, 34, 36) is connected to one of the power switching assemblies (29, 30, 31) to supply a consumer (33, 35, 37). The first terminal of the assembly is electrically coupled to a first bus section (20) and the second terminal is electrically coupled to a second bus section (21). First and second semiconductor devices (114, 116) are electrically coupled between the terminals to control current flow between the terminals and there is a current connection (124a, 124b) from each terminal to a power switching assembly controller (126) for providing an indication of current at each terminal. A control signal line (128, 130) is connected between the power switching assembly controller (126) and each semiconductor device (114, 116) for providing a control signal to the semiconductor devices to control the current flow through them and an inverter coupler (40, 41) couples each current [Continued on next page] WO 2018/028976 Al MIDEDIMOMOIDEIREIDIONMEMOMERMOVOIS SC, SD, SE, SG, SK, SL, SM, ST, SV, SY, TH, TJ, TM, TN, TR, TT, TZ, UA, UG, US, UZ, VC, VN, ZA, ZM, ZW.
