Abstract :
A method to improve the output voltage of DC-DC converters against source and load fluctuations is proposed in this paper. The proposed method is based on a new concept of virtual L and C filters that are connected on the output of DC-DC converters. Virtual L and C filters are used to minimize the effect of source voltage and load current fluctuations, respectively, on the output voltage of converter. Virtual L and C filters are additional control algorithms that emulate the effects of L and C filters on the output voltage of converters. The virtual L and C filters are designed to respond only against disturbances. Simulated results are included to verify the proposed method
