Block Analysis of a Voltage Supply Chain: Mixed Electromagnetic Modeling and Validation

This paper describes an industry-oriented approach for the analysis of complex electronic systems. The typical constrains of an industry design flow such as limited time, limited computing resources, and the use of standard/commercial software tools are considered. The approach consists in partitioning the system in several functional blocks and studying each block separately. Different numerical techniques are employed, choosing the more appropriate, for characterizing each chain blocks. At the end, all the blocks are cascaded obtaining the overall system performances. The approach is applied to a voltage supply chain mounted on board of the SENTINEL 1-SAR satellite to verify the integrity of the voltage pulse propagating from the source to the high power amplifiers. The final results are validated by hardware measurements.
