AUTONOMOUS PORTABLE POWER GENERATOR Russian patent published in 2013 - IPC H02K47/14 

FIELD: electricity.

SUBSTANCE: design applies a miniature two-stroke or a four-stroke internal combustion engine with the volume of the combustion chamber in the range of up to 2.5 cm³ and rated speed of rotation of up to 15000 rpm, and therefore, low fuel consumption, and a miniature synchronous generator with permanent magnets, an electronic unit of system control, comprising a controlled synchronous rectifier, to the input of which alternating three-phase voltage is supplied from the miniature synchronous generator, a unit of an energy accumulator, providing for uninterrupted operation of a device under sharp load changes, a voltage stabiliser, to the input of which rectified voltage is supplied, and the stabilised voltage arrives to a powerful current inverter, which generates the equivalent AC voltage required to the consumer.

EFFECT: increased output capacity and specific power intensity of a power generator, which is portable and hand-carried due to reduction of weight of an internal combustion engine, a simple-to-use low-sized autonomous source of power supply.
