FEATURES SWITCHING PROCESSES AC DRIVE WITH TRANSISTOR VOLTAGE CONVERTER

Considered switching processes in AC voltage regulator, a comparison of the spectra and quality parameters of the output voltage of three-phase voltage converters in the formation of different kinds of pulse width modulation sinusoi-dal. The criteria of evaluation of the quality of the output voltage converter with pulse-width modulator pulse width modulation defined methods for forming a pulse width modulation, providing the best quality of the output voltage. The possibility of reducing the energy losses in the power semiconductor switching voltage regulators. Shows how to improve the performance quality of the output voltage, reduce losses, improve the fundamental harmonic relationship to the supply voltage.
