This paper proposes a new design approach for two non-identical converters connected in parallel to obtain higher efficiency across the load range. This is achieved by allowing one converter to be designed for efficiency, without being constrained by system requirements, such as the transient response and current ripple, which will be met by the second converter. The efficiency of the proposed parallel converter is compared to an interleaved converter, both in theory and in practice. (6 pages)
