Webmaximum duty ratio at which the converter can operate. The duty ratio is defined as the on-time of the MOSFET divided by the total switching period. In all DC/DC converters the output voltage will be some function of this duty ratio. For the boost converter the approximate duty ratio (D) can be found with Equation 4. WebA boost converter waveform comprises two components: a nominal (average) DC output and noise generated by the switching waveform that appears as a ripple around the …
