Duty cycle of buck converter formula

WebMar 10, 2024 · In Simulink I am creating a DC-DC buck converter using Average-model based VSC Universal. But in VSC one input is Uref. For this case I need to convert a Duty Cycle (D) into Uref for Input. But what is the name of model for converting Duty-cycle to Uref. From a simulink diagram I also find the picture of that converter. WebAs a rule of thumb, it is usually recommended to start a converter design with a 30% to 40% ripple current. This leads to a nominal inductance (L), calculated with Equation (1): L=(1−DC)×( V OUT fsw×ΔIL) L = ( 1 − D C) × ( V O U T f s w × Δ I L)
