  "textContent": "A propulsion system is provided that includes an energy system (102), an auxiliary system (104), and a system controller (106). The energy system (102) includes a bi-directional boost converter (112) coupled to a direct current (DC) link and comprising a plurality of input channels (a,b). The energy system (102) also includes a first energy storage device (108,110) coupled to a first input channel (a,b) of the bi-directional boost converter (112) via a DC bus. The auxiliary system (104) is coupled to the energy system (102) and includes an auxiliary energy source (110, 126, 164), an auxiliary load (130, 134, 158), and an auxiliary load controller (132, 136, 160) coupled to the auxiliary energy source (110, 126, 164) and to the auxiliary load (130, 134, 158). The system controller (106) is configured to cause the auxiliary load controller (132, 136, 160) to reduce a power draw of the auxiliary load (130, 134, 158) from the auxiliary energy source (110, 126, 164) and to cause the bi-directional boost converter (112) to boost a voltage supplied by the auxiliary energy source (110, 126, 164) and to supply the boosted voltage to the DC link (114).",
