Dc-Dc converter with reduced input current ripples

   
   

An improved DC-DC converter with reduced input current ripples. The converter includes a transformer, a switch, and a capacitor. The switch turns on and off alternately to store the energy in the transformer. The capacitor is connected in series with a rectifier and a secondary winding of the transformer across an input DC voltage so as to be charged by the energy released from the secondary winding through the DC power source. Accordingly, the circuit sees an input current which continues flowing through the DC power source even the switching element is turned off.

Um conversor melhorado de DC-DC com corrente reduzida da entrada ripples. O conversor inclui um transformador, um interruptor, e um capacitor. O interruptor gira sobre e para armazenar fora alternadamente a energia no transformador. O capacitor é conectado em série com um retificador e um enrolamento secundário do transformador através de uma tensão de C.C. da entrada para ser carregado pela energia liberada do enrolamento secundário com a fonte da alimentação de DC. Conformemente, o circuito vê que uma corrente da entrada que continue correndo através da fonte da alimentação de DC Mesmo o elemento do switching está desligada.
