DC-DC Converter Auxiliary Design Using the Microsoft Excel

The DC-DC converter design and implement software using in Excel was introduced. Taking a multi-output Forward converter design for example, the auxiliary circuit Excel software application design ideas, methods and points were given. The powerful data via Excel calculations was used to complete the design process of the formula and parameters for finishing operations. The database data via Excel call and other functions were used to complete the circuit design of each power device selection and the magnetic component design. VBA programming language optimized software interface was used to solve the main problems about conventional circuit design, such as the efficiency estimates, iterative calculation, duty cycle control lost and so on.
