WebMay 22, 2024 · I found a formula for the DC transfer function for the flyback converter: V o u t V i n = N s N p ⋅ D 1 − D where N s N p must be the ratio between the number of turns of the two coil-inductors, and D is the duty cycle. And since we know V o u t and V i n, we just need to find N s N p, and then we can solve the equation with respect to D. WebIpk= C*dV/dt C= Ipk*dt/Vrail We want to only affect the leading edge of the rising voltage and so the time constant (TC) of the RC element must be a fraction of the period. We use the time constant formula for choosing R. RC= TC A rule of thumb is to choose Tc to be 1/10th the switch on time.
