| Abstract: | This paper studies the pulse width modulation(PWM) control technology for multiphase DC-DC circuits,compares the current-mode PWM controllers with the voltage-mode PWM controllers,proposes a current-mode control method based on the rapid active current averaging technology,and applies it to project design.Experiments show that the influence of component mismatching is eliminated by using the rapid active current averaging technology. |
