A novel single- to three-phase static converter

A comprehensive analysis of a phase converter structure capable of providing three-phase AC power from existing single-phase AC mains by using the principle of cycloconversion is presented. The proposed converter provides balanced three-phase output power and generates a low-distortion input current. However, output voltages contain low-order harmonics which can be easily filtered. The simple control logic circuit and the six-switch converter configuration required make the proposed phase conversion scheme attractive economically as well as practically. Experimental results obtained on a laboratory prototype have been used to prove the validity of respective predicted results.>
