The analysis of a number of the latest world researches on modularity of power supplies, electronic systems for the power interface of modules, and also the last researches on construction of multiphase fault-tolerant electric machines is carried out. As a result of this analysis, it was concluded that energy-efficient and highly reliable EAV can be built by combining the modularity of on-board power supply systems with the modularity of electric machines. In addition, these subsystems must be unite by common systems of power semiconductor converters of different configurations with increased degrees of freedom, thanks to which it is possible to realize multi-purpose control of work of EAV. The method of structural synthesis of the passive system has been developed in order to quickly obtain all possible options for the formation of control effects, which provide a number of requirements of the energy management system. The effectiveness of this direction is confirmed by the conducted simulation researches of work of PBC HESSs of various configurations. The algorithms and programs have been developed that simultaneously effectively control the electromagnetic torque and speed of the BLDSM, as well as provide equalization of B`s charges in the modules. Mathematical modeling of the magnetic field, by the finite element method in the two-dimensional formulation, of different variants of a six-phase synchronous machine with permanent magnets (PMSM) with a two-module three-phase armature winding and symmetrical and asymmetric modules shifted at different angles. An algorithm for calculating the magneto-mechanical characteristics of a modular PMSM has been developed. This algorithm is designed to calculate the steady-state values of mode variables and size optimization, winding data for multiphase machines with fractional ratio of the number of armature teeth per pole and phase Z/p/n at the stages of their initial design, as well as modeling of dynamic processes.
