Progress in Signals and Telecommunication Engineering Svilen Stoyanov, Desislava Mihaylova 10 2 2021 https://www.dline.info/pste/fulltext/v10n2/pstev10n2_3.pdf We have introduced a method of bidirectional converter with frequency deviation. It has low power output and low power consumption which work on ramp conversion. Besides, we have also developed a mathematical model of the convertor. While we tested in real life we found that the model is designed for measuring forces and torques in different technological processes. The experimental outcome is given extensively and summarized.
