DC-DC Converters
Every dc-dc converters calculator on CalcEngines — unit converters, derived indices and interpretive tools, each with its formula, a worked example and the reference intervals it is judged against.
6 calculators in this section
- Boost Converter DesignerDesign the power stage of a step-up (boost) converter: duty cycle, inductance, input and peak currents, RMS currents, output capacitance and ESR for a ripple target, the right-half-plane zero and the nearest standard parts.
- Buck Converter DesignerDesign the power stage of a step-down (buck) converter: duty cycle, inductance, peak and RMS currents, minimum output capacitance and ESR for a ripple target, the CCM/DCM boundary, and the nearest standard inductor and capacitor.
- Buck-Boost Converter DesignerDesign an inverting buck-boost converter, which makes a negative output from a positive input: duty cycle, inductance, peak and RMS currents, switch voltage stress, output capacitance and ESR, the right-half-plane zero and standard parts.
- Flyback Converter CalculatorFirst-pass flyback design from the input range, output and switching frequency: turns ratio, reflected voltage, primary (magnetising) inductance, peak and RMS primary current, MOSFET drain voltage stress and output diode reverse voltage.
- Forward Converter CalculatorDesign a single-switch forward converter with a reset winding: turns ratio, duty cycle across the input range, output inductor and capacitor, magnetising current, the reset duty limit, MOSFET voltage stress and the ratings of all three diodes.
- Ćuk Converter DesignerDesign an inverting Ćuk converter: duty cycle, both inductors, the coupling capacitor's voltage, ripple and RMS current, the output capacitor, switch and diode stresses, and the load below which it leaves continuous conduction.
