FIELD: machine building.
SUBSTANCE: invention relates to automotive industry. Power system of on-board network of hybrid vehicle using engine exhaust gas energy includes turbo generator connected to exhaust system, AC to DC converter connected to the turbine generator, DC to DC converter, which is connected to the AC to DC converter. DC to DC converter consists of low-voltage and high-voltage part and is connected with alternating-current converter into DC. DC to DC converter allows to transmit energy generated by turbogenerator simultaneously to on-board network and traction electric drive network and to control power flows from vehicle on-board network to traction electric drive network, as well as to feed low-voltage on-board network of vehicle and high-voltage part supplying traction electric drive and energy storage buffer.
EFFECT: improved efficiency of electric energy use.
