N2 - This paper presents a new topology of fuel cell /lithium battery hybrid unmanned aerial vehicles (UAV) based on three-switch control, in which hydrogen fuel cell is the main power and lithium battery is the auxiliary power. In this proposed topology, three power switches and two unidirectional DC/DC converters are used. Three switches can be controlled to switch between different states, and the DC/DC converter can be controlled to realize power distribution. This method combines the advantages of the two traditional hybrid power system topologies described in this paper, effectively improves the output efficiency of the system, reduces the control complexity, and can control the charging current of the lithium battery. In addition, a multi-energy management strategy is adopted in this paper. In this strategy, for different flight profiles of UAV, corresponding optimal control strategies are adopted to improve the dynamic characteristics and fuel economy of UAV. Also, several commonly used control strategies are compared, including the state machine control strategy, the power following control strategy and the equivalent consumption minimization strategy (ECMS). Finally, a ground test platform is built to verify the effectiveness of the topology and algorithm.
