Abstract
This paper presents a new implementation of resonant switching on the dc side in power converters, which can significantly reduce the energy of dynamic losses with a minimal amount of additional elements. These methods are carried out on the basis of the notion of resonant switching by integrating its structure into the input circuit of the converter. Resonant switches of the first and third type switched at zero voltage and resonant switches of the second type switched at zero current are used in the voltage inverters. Dual resonance switch options are used in the current inverters. Basic variants are considered in which the resonant circuit has a direct connection with the input voltage or current source, as well as converter circuits with an additional switch. The active resonant process control is used in all variants, which is synchronized with the PWM control of switch elements of the converter.
