Abstract:
1. An electrical power supply system for an aircraft comprising: an electrical network including at least one main generator feeding at least one technical load and at least one commercial load through at least one electrical power distribution channel including at least one electrical distribution busbar and at least one voltage converter, wherein the electrical network is divided into multiple sub-networks, a galvanic isolation using voltage converters being established between the sub-networks, wherein first sub-networks of the multiple sub-networks correspond to a high power technical load and are protected using an IT type grounding with neutral isolated from ground or having a high impedance, and second sub-networks of the multiple sub-networks correspond to the commercial loads and a low power technical load, the second sub-networks being protected by a TN-C type grounding.
