In this applet the dynamic behaviour of the buck converter can be examined. Step changes in input voltage, load resistance and duty cycle can be applied separately or as a combination. The waveforms show how the currents and voltages in the circuit are affected by a step change in operating conditions.

• Click on the red text to toggle the parameter to its other value.
• Adjust each parameter in turn and observe the step changes in the waveforms and how quickly the transient takes to return to steady state.
