A closed loop boost DC-DC converter with novel capabilities of fuzzy logic controller is proposed, which mainly meant for constant power loads. The fuzzy logic controller controls the system to achieve constant output as per the requirement of the load. Due to the variation of input voltage and load current, a two stage ZVT (Zero Voltage swiTching) boost converter with series resonant convertor is used to give supply to the load. The selected converter has the advantage of No duty cycle loss, wide Zero Voltage Switching (ZVS) range, no ringing problem of the rectifier.
