SpletThe buck converter is a form of DC to DC converter, which can take a DC input directly from a DC source, such as a battery, or as shown in Fig. 3.1.1 from the rectifier/reservoir capacitor circuit. This DC is then converted to AC, using a switching or ‘chopper’ transistor, driven by a (usually pulse width modulated) high frequency square wave.
