Abstract

"APARELHO DE FORNECIMENTO DE ENERGIA CONECTADO A UMA CORRENTE ALTERNADA PARA OBTER UMA TENSãO DE CORRENTE CONTìNUA ESTABILIZADA, APARELHO ELETRôNICO, E, ADAPTADOR DE CA". Primeiro, segundo e terceiro capacitores (11, 12, 13) tendo valores de capacitância predeterminados são conectados em série em uma linha de corrente alternada comercial. Uma ponte retificadora (14, 15, 16, 17) incluindo dois diodos (14, 15) tendo características reversas ajustadas em uma tensão de Zener é conectada em paralelo com o capacitor (12) no centro, e um capacitor de alisamento é conectado entre uma extremidade e a outra extremidade da ponte retificadora (14, 15, 16, 17). Como resultado, é possível dividir CA de um terminal de entrada de potência em uma tensão desejada enquanto isolando-a, e corta-la com uma tensão predeterminada para forma-la em uma forma de onda de tensão próxima a uma onda retangular e alisa-la. Por meio disso, uma tensão de CC estabilizada com menos ondulações pode ser obtida.
