3.2. Power Stage GUI

The Power Stage GUI (Figure 3) shows a single-phase buck topology. The user enters values for the converter

input voltage (Vin), the filter components (inductor and associated series resistance, capacitor and associated

series resistance), and the output load resistance value. The up/down buttons associated with each field allow the

user to increment or decrement the specified values by simply clicking on the appropriate button. As with all other

GUIs in this tool, the specified values may also be changed by simply typing over them, then pressing the ENTER

key.

Although a single-phase schematic is shown, a multiphase circuit can be modeled by adjusting only the

inductor parameters. For instance, an equivalent two-phase design would include two equally sized inductors

whose values are one-half that of a single-phase design. To model this, both the inductor's DCR and L values need

to be adjusted accordingly. All other parameters in the model remain the same.
