Abstract

Patente de Invenção: <B>"CONVERSOR DE FREQuêNCIA E FONTE DE ENERGIA ININTERRUPTA QUE EMPREGA O MESMO"<D>. Uma fonte de energia ininterrupta (UPS) inclui um transformador; um conversor de voltagem baixa (02); um retificador e um inversor de voltagem elevada (01). O conversor de baixa voltagem compreende uma bateria, um primeiro dispositivo de comutação (Q3), um segundo dispositivo de comutação (Q4) e primeiros circuitos impulsores (41, 42). O inversor de voltagem elevada (01) inclui primeiro e segundo terminais de carga adaptados para serem acoplados através de uma carga em uma situação de emergência; um capacitor de saída (C); um terceiro dispositivo de comutação (Q1) e um quatro dispositivo de comutação (Q2), e segundo circuito de impulsor (43, 44) para impulsionar os terceiro e quarto dispositivos de comutação, dos estados condutor e não-condutor, e vice-versa, de modo a produzir uma forma de onda de voltagem de saída quase sinusoidal através de terminais de carga.
