Abstract :
A multivariable adaptive digital controller to optimize DC-DC converter switching frequency and dead- time at the same time, for maximum efficiency under variable conditions, is presented in this paper. The multivariable adaptive digital controller (MVAC) adaptively adjusts the DC-DC converter switching frequency and dead-time while tracking the converter minimum input power (maximum efficiency) point under variable conditions including variable load and variable input voltage. In this paper, the MVAC method is discussed analyzed and its digital control algorithm and experimental results are presented.
