Description

Power Stage Designer™ Tool helps design the power stage of the most commonly used switchmode power supplies. It is also a great assistance for getting a deeper understanding of voltages and current flows inside converters.

How To Use

  • Choose the adequate topology on the main screen or in the "Topology" menu for your demands.
  • Fill out the "Design Values" with your values and requirements. When you place the cursor on a respective input field, on some fields a note with hints will appear.
    NOTE: If a field turns red, you will need to reconsider your inputs and results.
  • Check the "Recommended Values" for the proposed values of the inductor and/or transformer. The inductance of the output filter is calculated to achieve the desired current ripple at all input voltages. The turns ratio shown is the maximum possible value to achieve the desired maximum duty cycle. Choose a turns ratio equal to or smaller than the calculated to stay below the maximum duty cycle. The transformer inductance shown is calculated to achieve the desired magnetization current at average input voltage.
  • Fill out the input fields of "Choose Values". Use the "Recommended Values" to choose an adequate inductor and/or transformer from your supplier.
  • Below the schematic of the switch mode power supply, under "Calculated Values", all relevant information is shown. You will see for example the duty cycle, input power, losses on the diodes, current ripple and much more. Depending on the topology different information is shown. With the shortcuts CTRL+1, CTRL+2, CTRL+3 the input voltage can be changed between minimum, average and maximum input voltage. The average input voltage is the minimum added to the maximum input voltage and divided by two.
  • The yellow highlighted parts on the schematic are clickable. A new window appears and shows the voltage and current of the selected part. Additional information is shown below the graphs. The input voltage can also be changed by the buttons shown on the bottom right side.
  • The "Info" button opens a new window and shows additional information about the shown topology such as links to application notes and datasheets.
