Abstract

This paper shows that double-diode rectifiers can generate 12-step voltages by using well-designed line-side reactors, although with relatively large self-inductances. The usage of three-level rectifiers can alleviate this disadvantage. The double three-level rectifier system proposed features the following advantages over conventional transformer-coupled systems: small in size, light in weight, and more economical; control capabilities of output DC voltage in a limited range; low current and voltage ratings required for additional circuits; and highly reliable operation due to 12-step operation capability without additional circuits
