Abstract: The invention relates to a drive system (10), in particular for a vehicle, comprising a fuel cell unit (12) for generating electric energy, a secondary battery (14) for storing electric energy, an electric machine (20) with windings (21, 22, 23), and an inverter for actuating the electric machine (20). The inverter (30) is designed as a 3-level inverter and has multiple electronic switches (S1, S2, S3, S4, S5, S6, S7, S8, S9, S10, S12), diodes (D1, D2, D3, D4, D5, D6, X1, X2, X3, X4, X5, X6, X7, X8, X9, X10, X12), a plus pole (37), a minus pole (35), and a neutral pole (36). The fuel cell unit (12) and the secondary battery (14) are connected in series and are connected to the poles (35, 36, 37) of the inverter (30).
