Energy-efficient inverter circuit for the low-voltage asynchronous driver controller with autonomous power supply

The design of the energy-efficient inverter circuit for asynchronous frequency-controlled three-phase electric driver with autonomous low-voltage DC power supply. components analysis drive, main selection approach: microcontroller, and transistors. R&D prototype was created, characterized by an average consumption current reduced 5%. Reducing energy losses is achieved reducing dynamic in circuits a using several solutions.
