What is the duty cycle in a boost converter and how is it calculated?

The duty cycle represents the fraction of time the switch is closed during each switching period. It is calculated based on the ratio of input to output voltage, with the formula D = 1 - (Vin / Vout), where Vin is the input voltage and Vout is the desired output voltage.

How do I choose the right inductance value for my boost converter?

The calculator determines the minimum inductance required based on your input voltage, output voltage, switching frequency, and load current. A larger inductance reduces ripple current and improves efficiency, but increases size and cost, so the calculated value serves as a practical starting point for component selection.

Can this calculator account for efficiency losses in real circuits?

No, the tool provides calculations based on ideal steady-state assumptions. Real-world efficiency losses due to switching transitions, conduction resistance, and other factors will affect actual performance, so the results should be validated through simulation or prototyping.

What switching frequency should I use for my boost converter design?

The switching frequency is a design choice that trades off between inductor size and switching losses. Higher frequencies allow smaller inductors but increase switching losses in the transistor, while lower frequencies reduce losses but require larger magnetic components. The calculator uses whichever frequency you specify to determine the resulting duty cycle and inductance.
