Autonomous Invertor of Current

Invention relates to electrical engineering, and it can be used for the electrical drive. Its aim is to improve the current form factor. Invention contains two autonomous dc sources 1 and 9, each connected in a series with controlled switches 2 and 10. At least two controlled frequency generators 5, 6, and 11, 12 are attached to each of the switches, said generators being associated with programmable timers 7, 8 and 13, 14. Surge limiter 3 is connected in parallel to RL load 4. In a certain range of angle it forms unipolar pulses with current increase and decrease, providing a sinusoidal current character.
