PowerEsim is simulating the power supply in power supply unit (PSU). In this case the device is more accurate to be referred as a "power converter" than a power supply.Ībout Power Supply Unit, Switching Mode Power Supply (SMPS) and PowerEsim This kind of electronic system converts electric energy to mechanical energy from the source to a given load. The “Info” button opens a new window and shows additional information about the shown topology such as links to application notes and datasheets.PowerEsim, a free (SMPS) switch mode power supply design software and Transformer Design, Magnetic Design, Simulation,Calculation Software Tool What is Power Supply/Power converter?Įlectric energy is transformed to be the engine of any power supply. The input voltage can also be changed by the buttons shown on the bottom right side. Additional information is shown below the graphs. A new window appears and shows the voltage and current of the selected part. The yellow highlighted parts on the schematic are clickable.
The average input voltage is the minimum added to the maximum input voltage and divided by two. With the shortcuts CTRL+1, CTRL+2, CTRL+3 the input voltage can be changed between minimum, average and maximum input voltage. Depending on the topology different information is shown.
You will see for example the duty cycle, input power, losses on the diodes, current ripple and much more. Use the “Recommended Values” to choose an adequate inductor and/or transformer from your supplier.īelow the schematic of the switch mode power supply, under “Calculated Values”, all relevant information is shown. The transformer inductance shown is calculated to achieve the desired magnetization current at average input voltage.įill out the input fields of “Choose Values”. Choose a turns ratio equal to or smaller than the calculated to stay below the maximum duty cycle. The turns ratio shown is the maximum possible value to achieve the desired maximum duty cycle. The inductance of the output filter is calculated to achieve the desired current ripple at all input voltages. NOTE: If a field turns red, you will need to reconsider your inputs and results.Ĭheck the “Recommended Values” for the proposed values of the inductor and/or transformer. When you place the cursor on a respective input field, on some fields a note with hints will appear. How To UseĬhoose the adequate topology on the main screen or in the “Topology” menu for your demands.įill out the “Design Values” with your values and requirements. It is also a great assistance for getting a deeper understanding of voltages and current flows inside converters. Power Stage Designer™ Tool helps design the power stage of the most commonly used switchmode power supplies.
