Abstract
Pre-conditioners (or line-conditioners) are used to convert electrical power having first characteristics into electrical power having second characteristics. For example, a pre-conditioner may connect electrical equipment forming a load, which requiring only a conventional mains supply level to a utility three-phase supply. This means that the power components of the load may be de-rated, making the load electrical equipment cheaper. Such circuits may be further improved. Components in the down-converter itself still need to be rated to interface with the higher voltage. An approach is proposed in which two interleaved down-converters () can be used to supply voltages. An energy recovery element () connects snubbers of the interleaved down-converters, thus enabling some de-rating of the pre-conditioner circuitry.
