This article discusses the development of three-phase valve converters with a steeply external characteristic consisting of a parametric current source, to the outputs of which three-phase valve kits are connected. A parametric current source, made according to the "star" scheme, converts the initial three-phase EMF system into a three-phase current system; the resonant circuit of the parametric source improves the energy performance of the valve converter, it contributes to the growth of energy efficiency indicators. Three-phase converters with a steeply falling external characteristic are most appropriate in practice when using them as power sources for energy-intensive consumers of electrical technology, which, ultimately, leads to an increase in the quality of products.
