成果简介	NOVELTY - Invention relates to electrical engineering and is intended for converting DC voltage into three-phase AC voltage. At the output of the single-phase bridge circuit of the inverter there is an L-shaped LC filter and a control unit for the converter, which implements PWM and stabilization of the output voltage by the inverter. In the stabilization unit, a sawtooth signal is used as a reference signal, and a DC voltage is used as a driving signal, which is proportional to the output voltage of the converter. Converter comprises inverter power circuit (1) comprising input capacitor (5) connected to DC voltage source US, transistors (6 and 7), switches (K1 and K2), output L-shaped LC-filter (2) containing inductance coil (25) and capacitor (26), transformer with rotating magnetic field (3), containing first and second primary windings (20 and 21), respectively, phase-shifting capacitor (8), secondary windings (22–24). Control unit (4) comprises voltage deviation meter 19, sinusoidal waveform driving generator (18), adder (17), rectifier (16), pulse former (13), triangular voltage generator (11), AND logic elements (10 and 15), voltage polarity sensor (12) and pulse amplifiers (9 and 14). USE - Electrical engineering. ADVANTAGE - High quality of output voltage and reliability of converter operation. 1 cl, 2 dwg
