WebThe duty cycle for the inverting topology is the same as that of the Cuk converter, namely Duty Cycle (D) = V OUT /(V OUT – V IN ) Similarly, given the same output voltage, input voltage and switching frequency, the circuits have the same duty cycle and the same inductor current slope (namely the ripple current, which equals V IN* t ON /L). WebThe efficiency is added to the duty cycle calculation, because the converter has to deliver also the energy dissipated. This calculation gives a more realistic duty cycle than just the equation without the efficiency factor. Either an estimated factor, e.g. 80% (which is not unrealistic for a boost converter worst case efficiency), can be how does an online store work
