| Abstract: | The existence of periodic solutions for closed-loop PWM DC-DC buck converter was studied by means of the equations of periods. A sufficient condition of the existence of its periodic solutions with only one switching within a period was derived. The result given was helpful for the design of controller and selection of parameters of the carrier signal with sawtooth characteristic in the closed-loop PWM DC-DC buck converter. |
