Abstract

"FONTE DE ALIMENTAçãO E MéTODO PARA AQUECER OU FUNDIR INDUTIVAMENTE UM MATERIAL ELETRICAMENTE CONDUTIVO". Uma fonte de alimentação de retificador/inversor (10) para uso com aparelhos de aquecimento ou fusão por indução inclui um capacitor de sintonia (C~ 1~) conectado através da saída do retificador (14) e entrada do inversor (20). O capacitor de sintonia (C~ 1~) forma um circuito ressonante com uma bobina de carga indutiva (L~ 9~) à freq³ência operacional do inversor (20). Adicionalmente, a bobina de carga (L~ 9~) pode compreender uma bobina de carga ativa conectada com a saída do inversor (20) e uma bobina de carga passiva, em paralelo com um capacitor de sintonia ressonante, para um circuito de eficiência aperfeiçoada.
