Pulse-frequency-width adaptive alternating voltage regulator with integrating control system

Abstract

The principle of constructing the alternating voltage regulator with pulse-frequency-width modulation capable to adapt to non-stationary condition of electric power supply is considered. The structure of a control system and its timing waveform diagrams is reduced. Is shown, the such regulators have practically unlimited adjustment range, extended precision and noise stability due to application in the control algorithm of an integrating sweep conversion method. The control system of the drying camera, which consists of an adaptive alternating voltage regulator and continuous monitoring system of isolation of a product exposed to thermal processing is developed.

The paper is intended for the scientific and engineering workers specializing in the field of power converter engineering as well as can be of interest for the students of a power direction.

Keywords: alternating voltage regulator, pulse-frequency-width modulation, pulse-width modulation, amplitude modulator, integrator, element relay.
