    How to Select Inductor for Boost Converter

    1. Select Inductance Value a. Define the switching frequency for the boost converter Example: Fsw = 300kHz b. Define the input and output voltage Example: Vin = 12V, Vout = 24V c. Determine the duty cycle Dutycycle = 1 – (Vin / Vout) Example: Dutycycle = 1 – (Vin / Vout) = 1 – (12V / 24V) = 50% d.

    How to Calculate Boost Converter Ripple Current

    In early stage of the design, boost converter ripple current is can be assumed as 25-40% of the RMS input current. But how to calculate boost converter ripple current from the design itself? This will be answered below, so better keep on reading. The 25-40% is just a pre-assumption value and can be changed depending on a specific need and

    How to Calculate the Duty Cycle of Boost Converter

    The inductor waveform is the key on how to calculate the duty cycle of boost converter. You can get direct equation for boost converter duty cycle formula from different sites but here I will discuss how it is derived. Meanwhile, a familiar boost converter schematic is shown in Figure 1. Figure 1 The inductor of the boost converter charges during
