Abstract

The article presents the design of a two-channel solid-state converter which can be used to match the output characteristics of distributed generation sources and an electrical network. The study purpose is to consider the processes that occur during the parallel operation of two input converters - an active rectifier and DC/DC converter on a common capacitive storage. The simulation results showed the need to make changes to the design of the device, as well as to the converter control system. Cut-off diodes are added to the output circuit of the DC/DC converter. The two-channel solid-state converter provides sine wave active current draw from an AC power source and low ripple DC current draw from a DC power source.
