Neuro Fuzzy Based Auxilary Switch Control of a Bidirectional DC-D Converter

The auxiliary switch control using a neuro fuzzy technique is proposed to enhance the efficiency of bidirectional converter used in electric vehicle which performs soft switching. Continuous current data are difficult to obtain during a resonant operation due to limit of DSP ADC capacity. The auxiliary switch control has a lookup table reference of the turn on time. The ANFIS controller properly controls the auxiliary switch turn on time according to the required load current, this auxiliary switch control brings the more efficient control in generative and regenerative more operation.
