Abstract :
An adaptive digital controller with maximum efficiency point tracking to optimize the FETs´ switches driving-voltage is presented in this paper. The driving-voltage-optimization (DVO) method adaptively changes the FETs driving voltage magnitude while tracking the converter minimum input current/power (maximum efficiency) point. The DVO digital controller continuously finds the optimum FETs driving voltage that will result in a minimum total combined FETs driving and conduction losses while converter parameters and conditions vary. In this paper, the DVO method is discussed analyzed, and its digital control algorithm and experimental implementation are presented
