Formation of the output voltage of the thyristor converter invariant to the change of the load parameters

Abstract

It was proposed to conduct a harmonic analysis of the output voltage of the ESRD with the replacement of the phase angle of the current φ by the angle of delay of the current δ. A model of the TPN-AD system with a mathematical block of the function α = f (δ; U1) was built, which allows it to be controlled with the required voltage value on the stator of the AD, compensate for internal positive feedback in current phase, get rid of unstable operating modes, and also do not take into account changes in the parameters of the replacement circuit of the engine.
