摘要：

Realization of a loss-free resistor element (i.e., element with resistive input characteristic and yet loss-free) by means of switched mode converters operated in discontinuous current conduction mode (DCM) is presented. Practically, the input characteristic is not pure resistive due to the ripple and filtering effects.,A, method which enables reduction of the ripple to negligible values and the elimination of the input filter is presented, which facilitates realization of practical circuits with nearly pure input resistive characteristic. This approach is based on the operation of a group of converters operating in power sharing interleaved mode.
