FIELD: electrical engineering.
SUBSTANCE: invention pertains to electrical engineering, and specifically to invertors for autonomous electrical power supply for different electrical equipment, requiring use of sinusoidal alternating current. The direct current converter has a generator of sinusoidal voltage, a driver-amplifier and a power electronic converter. The sinusoidal voltage generator with frequency f is in the form of a miniature motor-generator, the electric motor of which rotates with a stable velocity proportional to frequency f and the motor-generator controls the electronic breaker-splitter. The electric motor of the motor-generator works on direct or alternating current and can smoothly change speed of rotation.
EFFECT: obtaining an output voltage without distortions, comparable to a perfect sinusoid, increased reliability of operating in external electrical fields, wider range of applications and reduced costs of manufacturing.
