FIELD: electricity.
SUBSTANCE: invention relates to an electric system to start an engine (18, 20, 22), comprising a rectifier (12) of AC into DC of AC voltage into DC voltage supplied from a power AC network (14), to produce the first DC voltage Vdc, a module (16) of DC conversion into AC to produce AC voltage of engine start with the help of the first DC voltage Vdc, comprising k parallel installed n-phase inverters (k>1), generating power that is at least twice lower than the maximum power Pmax, required to start the engine, and two lines of power supply of each inverter are connected to an electronic protective device receiving the first DC voltage Vdc, and n outputs of each inverter produce AC voltage of engine start via n serially connected inductance coils.
EFFECT: minimisation of mass of equipment required to ensure engine start.
