Estudo e implementação de uma carga eletrônica baseada em um conversor CC-CC

Abstract

The test of electronic products, during its manufacture, is a very important step to validate its operation, ensure the reliability and quality. Equipment such as sources, converters and triggers require a load simulation to reproduce their actual application. It is possible to use resistive loads, however, this becomes inflexible and with low accuracy, the electronic loads available in the market have a high cost, which makes it impossible to apply them in some productive processes that demand solutions with an affordable price. Faced with this difficulty, this project seeks to develop a simple electronic load, adapted to the application, low cost and easy implementation. The proposed electronic load is based on a DC-DC converter, with constant current at the input, where the load is simulated through the control of the converter. The work developed, reads the input voltage and current, through a PI controller, controls the drive input current. The interaction with the user is done through a graphic interface, present in the device itself, or through a computer software, which remotely controls the electronic load through serial communication (sic)
