É proposto um carregador de bateria de íons de lítio baseado em comutação sem qualquer circuito de compensação adicional. O carregador proposto adota um sensor de corrente dupla e um controle de janela de corrente para garantir a estabilidade do sistema em diferentes modos de carga: corrente lenta, corrente constante e tensão constante. O carregador de bateria de íon-lítio proposto possui menos área de chip e uma estrutura mais simples de projetar do que um carregador de bateria de íon-lítio convencional com modulação por largura de pulso. A simulação com um capacitor de 1000 µF como equivalente de bateria, uma entrada de 5 V e uma corrente de carga de 1 A resultou em um tempo de carregamento de 1.47 ms e uma eficiência energética de 91%.

Abstract: A switching-based Li-ion battery charger without any additional compensation circuit is proposed. The proposed charger adopts a dual-current sensor and a current window control to ensure system stability in different charge modes: trickle current, constant current, and constant voltage. The proposed Li-ion battery charger has less chip area and a simpler structure to design than a conventional Li-ion battery charger with pulse width modulation. Simulation with a 1000µF capacitor as the battery equivalent, a 5V input, and a 1A charge current resulted in a charging time of 1.47ms and a 91% power efficiency.
