Abstract(s)
Neste trabalho realizou-se o comando e proteção dos IGBTs em paralelo.
Apresentou-se o estudo teórico, o dimensionamento e a implementação experimental dos circuitos com os IGBTs em paralelo, utilizando os circuitos de disparo, de proteção contra sobrecorrentes e a técnica para equilíbrio de correntes.
Inicialmente realizou-se um estudo teórico e definiram-se as técnicas utilizadas neste trabalho. Seguidamente dimensionaram -se os circuitos de disparo dos IGBTs, de proteção contra sobrecorrentes e da técnica de equilíbrio de correntes. Posteriormente simularam-se os circuitos dimensionados. Por fim, retiraram-se os resultados experimentais a partir da implementação prática dos circuitos.
Abstract: In this work the control and protection techniques for IGBTs in parallel were applied. In addition, the theoretical study, the experimental design and implementation of circuits with the IGBTs in parallel was made, using the triggering circuits, protection against overcurrents and a technique for current balance. Initially, it was made a theoretical study and defined the techniques used in this work. Also, it was designed the triggering circuits of IGBTs, protection against overcurrent and current balancing technique which were subsequently simulated. Finally, experimental results were taken from the practical implementation of the circuit.
