Low-cost platform for electrical measurement and frequency analysis in power electronic education

In recent years, power electronics utilization in modern devices has experienced a large growth due to several applications. For this reason, undergraduate laboratory courses in this field should have modern equipment for measurement and analysis of electrical signals. With this, students will have the opportunity to understand theoretical concepts in practice. However, commercial equipment of this nature have high finance costs. This is an obstacle for undergraduate courses with financial restrictions. This paper presents the development and testing of a low-cost platform for electrical measurement and frequency spectrum analysis, conceived to improve power electronics education. Experimental results done with different types of loads, such as power electronics converters, demonstrated acceptable measurements when compared with commercial equipment.
