PWM buck convertersingle-loop controlvoltage-mode controlSummary This chapter explores voltage-mode control of the PWM buck converter. A buck PWM converter with negative feedback is illustrated. This control scheme is called voltage-mode control because the duty cycle is proportional to the control ...
This article mainly focuses on the development and implementation of a buck converter with a sliding mode voltage controller, to achieve the stable desired voltage output. Firstly, based on Lyapunov stable analysis, the controller is proposed to enforce the system trajectory from the arbitrary point ...

This paper discusses the effects of input voltage variations on the open loop and closed loop models of buck converter. Voltage Mode Control (VMC) has been proposed to develop an efficient closed loop system in order to avoid voltage fluctuations at the output of the buck converter. 展开 ...
In order to do this we need to modify the basic buck converter from Figure 18-3 to provide a voltage control input. The schematic in Figure 18-11 shows one way to control the duty cycle of the PWM waveform. The control voltage is compared to a sawtooth waveform using a comparator with...
