Abstract
A method includes determining an operating mode of a hybrid electric propulsion system. The hybrid electric propulsion system includes a conditionally regulated high voltage direct current (HVDC) architecture. The conditionally regulated HVDC architecture includes a first switchable circuit formed between an HVDC bus, an HVDC electrical source, and a bi-directional direct current to direct current (DC-DC) converter configured to regulate electrical power flowing between the HVDC bus and the HVDC electrical source. The conditionally regulated HVDC architecture also includes a second switchable circuit formed between the HVDC bus and the HVDC electrical source. The method also includes configuring the conditionally regulated HVDC architecture based on the determined operating mode.
