A Computer Aided Analysis and Design App

The design of static power converters often relies on the artful 'cut and try' method, leading to a lack of comprehensive analysis strategies for designing static converters with confidence. This paper addresses the challenges in designing static voltage source inverters by proposing a generalized analysis and design method. The primary objective is to derive essential analytical expressions using the switching function concept, supplemented by digital simulations to yield critical design data. Methodologically, the approach encompasses modeling the load accurately, identifying worst operating conditions, and developing a concrete static converter model. The research indicates that with an appropriate load model and a well-defined worst-case scenario, one can obtain the necessary ratings for component selection. Key findings highlight that a multifrequency AC current and/or voltage source model provides significant analytical insights when examining the converter through its input and output terminals. This innovative framework enables enhanced design capability and operational reliability for static voltage source inverters. The study underscores the importance of a systematic approach in the intricate design process of static converters.
