Abstract
Abstract—This paper presents an efficient and effective method
for an optimal pulse width modulated (PWM) control of
switched-capacitor DC/DC power converters. Optimal switching
instants are determined based on minimizing the output ripple
magnitude, the output leakage voltage and the sensitivity of the
output load voltage with respect to both the input voltage and the
load resistance. This optimal PWM control strategy has several
advantages over conventional PWM control strategies: 1) It does
not involve a linearization, so a large signal analysis is performed.
2) It guarantees the optimality. The problem is solved via both the
model transformation and the optimal enhancing control
techniques. A practical example of the PWM control of a
switched-capacitor DC/DC power converter is presented.
