Calculation Breakdown

  1. Applied FormulaCalculates the volt-second core reset balance, theoretical maximum operating duty cycle (D_max < 50% for 1:1 reset winding), and peak switch voltage for isolated forward converters.\int_0^{D T} V_{in} dt = \int_{D T}^{T} V_{in} \frac{N_p}{N_r} dt \implies D_{max} = \frac{1}{1 + N_r / N_p}
