【 摘 要 】

This article discusses development issue of semiconductor converters with the natural current external characteristics. The converter consists from a parametric current source, to the outputs of which are connected gated sets. The parametric source is a resonant circuit, which transforming electromotive force input system to the output system of currents. Here the resonant circuit in the current source provides an improvement in the power characteristics of the converter, so increasing energy efficiency indicators. This current converters use for supply most energy-intensive consumers with a steeply falling external characteristic (arc furnaces, electrolysis plants of non-ferrous metals, etc.), and also in electric drives with erection torque motor.
