A cycloconverter operates as a three-phase current source via three anti-parallel-connected SCR-bridges in a six-pulse configuration. Each cycloconverter phase acts selectively to convert fixed line frequency AC voltage to an alternating voltage at a variable load frequency. MC drives are IGBT-based.

Single Phase Power. Able to supply ample power for most smaller customers, including homes and small, non-industrial businesses. Adequate for running motors up to about 5 horsepower; a single phase motor draws significantly more current than the equivalent 3-phase motor, making 3-phase power a more efficient choice for industrial applications.
