A power transmission and distribution system includes a supplying side having a current source and a receiving side. The receiving side includes a modular converter with plurality of direct current (DC)-alternating current (AC) current source converters connected in series with the current source and a plurality of AC-DC rectifiers connected in parallel to supply power to a multiplicity of loads. Each of the DC-AC current source converters supply power to a corresponding AC-DC rectifier and includes a plurality of reverse blocking fully controllable switches having bidirectional voltage blocking capability. Furthermore, a current from the current source flows in at least one reverse blocking fully controllable switch at any instant.
