Abstract

This work presents the design and implementation of a control system for a thyristorized rectifier bridge held by PSoC (Programmable System-on-Chip), which is able to maintain the output current of the circuit in a predetermined reference supporting changes in input voltage, as well as changes in load. Using the PSoC — an integrated circuit that has programmable analog and digital resources — it is possible to reduce the external circuitry. The project built with the PSoC, compared with a conventional implementation, is smaller and has lower costs. Another important aspect is related to the decrease in energy consumption due to the use of fewer components. The rectifier and its control system were designed and simulated. Additionally, a prototype was built and the tests proved the feasibility of using PSoC.
