Abstract :
From the perspective of good point-of-load (POL) designs, a fast response for load-change and high power efficiency are important factors. Pulse width modulation (PWM) control is a common control method for POL. Although this control method is very simple and stable for POL, the response for sudden load change is not so fast because of its fixed frequency. However, pulse rate control (PRC) is well suited to such applications. The PRC control method and its features are described, and advantages of PRC are revealed with the some simulated and experimental results
