The invention discloses a main circuit of a hydrogen energy hybrid power machine, which is characterized in that a chopping module is additionally arranged in a traction converter to form a boost chopping discharge circuit and a buck chopping charge circuit on a power battery side together with an electric reactor, so that the voltage output to an intermediate direct current loop by a power battery is stabilized at DC1800V; meanwhile, the circuit safety of the power battery side is improved through the stable and controllable charging circuit; the hydrogen fuel power supply module directly obtains a starting power supply from the intermediate direct current loop through the bidirectional isolated voltage boosting/reducing module, and after the hydrogen fuel power supply module is started, the stability and timeliness of forward voltage boosting control of the voltage boosting/reducing module can be improved through the stable intermediate direct current loop voltage. According to the invention, consistency control of the intermediate voltage in different power supply modes is realized, and system faults caused by inconsistency of the intermediate voltage in the same main transmission system in different power supply modes are reduced. The invention further provides a railway vehicle.
