Abstract :
Battery-operated system such as cell-phone, digital camera becomes more and more popular. In this application, a boost-type converter is usually required to convert low battery voltage to high voltage application. In this paper, a variable frequency control of boost converter is discussed. The prototype circuit is built to prove the concept. The extension of this approach in power factor-correction application is discussed
