In view of the difficult situation with the recruitment of engineers and the efforts of the Todor Kableshkov University of Veliko Tarnovo to promote the opportunities and new specialties offered by the institute, we have realized an opportunity to support the candidate-student campaigns and our cooperation with the technicians.

A test bench for monophase rectifiers was designed and built to showcase part of the learning process and our work as lecturers. The special feature is that it has miniature dimensions, its own power supply and built-in: active, inductive and capacitive loads. Stand allows you to explore different types of rectifiers by simply switching multiple buttons. Load values can also be changed to allow for the realization of dozens of combinations and modes of work that cover part of the laboratory exercises in a number of

Stands are equipped with the necessary terminals for connecting a portable USB oscilloscope and measuring the current through the loads, it is easy to transport together with the accompanying equipment of each candidate-student campaign or a lecture delivered in a vocational high school. The report presents the main features and possibilities of the stand and the results of the tests.
