PowerSMPS is a technical blog about power supply design and experiments with embedded hardware. It covers component selection, design calculations, datasheet explanations and measurement results.
Topics
Articles cover SMPS and DC-DC converters, rectification and smoothing circuits, relay and motor control, gate drive, and EMI/EMC. The blog also documents converting and running AI models on embedded platforms such as RK3588.
How to read the articles
The articles distinguish calculations and explanations based on manufacturer documentation from experiments and measurements performed by the author. Calculations aim to state their assumptions and limits; experiments aim to describe their hardware, software and results. Unsuccessful attempts are also documented with the reasoning behind the conclusions.
Using the information
The blog is a reference for people designing power circuits and embedded systems or studying how they work. Numbers and examples apply to the stated conditions. Check current datasheets and verify the results in your own environment before applying them to a design.
