WebFig. 3.1.4 Buck Converter Operation Therefore if the switching waveform has a mark to space ratio of 1:1, the output V OUT from the buck Converter circuit will be V IN x(0.5/1) or half of V IN . However if the mark to space ratio of the switching waveform is varied, any output voltage between approximately 0V and V IN is possible. WebThe duty cycle of flyback transformers typically does not exceed 0.5. Various combinations of turns ratios and duty cycles can be used to achieve the required output voltage according to this equation: V out = V in * (N s /N p )* (D/ (1-D)) where: V out is the output voltage. V in is the input voltage. N s = secondary turns.
