Abstract: Systems and methods for transferring power delivery between power sources to an electrical bus are provided. More particularly, a multi-source electrical power system can include an electrical bus having at least two power sources that each can be selectively coupled to the electrical bus, for instance, via contactors. At least one of the power sources can include a unidirectional or bidirectional power converter. The electrical power system can further include a control system configured to control the power output (e.g., the output voltage and the output current) of the power converter to provide no break power transfer of power delivery to the electrical bus between the first and second power sources. In example embodiments, the no break power transfer can be achieved by regulating the output current of a power source to a fixed current value and/or by using a virtual resistance programmed into a voltage regulator.
