A Power Factor Corrector Boost Converter Based Memristor Emulator

Abstract

Analog and digital circuits are used to make memristor emulators. Power electronics circuits use switching to obtain the desired waveforms. A single-phase power factor corrector circuit is a well-known power electronics circuit. This study shows that a single-phase power factor corrector circuit can be used as a memristor emulator. To the best of our knowledge, there is no memristor emulator circuit made in this way in literature yet. This circuit employs a boost converter placed after the full-wave bridge rectifier. The power switch of the converter is controlled to obtain the desired memristive behavior by a microcontroller, STM32F429ZIT6. The circuit operation is examined using simulations and experiments. Also, a comparison is given between the proposed emulator and the other memristor emulators in the literature. Although the proposed emulator is able to emulate different memristor models described with varying window functions, only the results of the Biolek model are given due to space considerations. The circuit performs well and can easily emulate other memristor models after modification of its firmware for their window functions.
