DIRECT CURRENT DRIVE Russian patent published in 2016 - IPC H02P1/00 H02P1/04 H02P1/18 B60L11/04 B60L11/12 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering and can be used in a wide range of products as DC electric drive with independent power source of restricted power, for example, in service systems of spacecraft. Direct current drive with independent power source of restricted power consists of connector of electric motor, a capacitive power accumulator, commutation switches, network connector (for connection to power supply network), control switching device, motor revolution indicator, interfaced with axis of rotation of electric motor, a ballast resistor and isolation diode, connected in series in circuit of capacitance accumulator charging of electric energy from electrical network. Motor is started from previously charged capacitance accumulator (for example, supercapacitor unit), which ensures required starting current (and may exceed rated current by several times). When motor rotor turns, revolution indicator sends a signal to control switching device, which provides switching of electric motor supply to onboard power supply network.

EFFECT: technical result is uniform operation of autonomous power source, providing electricity network, without peak loads during start of DC motor, which increases reliability and service life of autonomous power source of limited power and enhances noise immunity throughout electricity network.
