Convertitori DC-DC

I convertitori DC-DC sono generalmente eseguiti come circuiti a 2 o 4 quadranti risonanti a cavallo di un trasformatore in media frequenza che realizza l’isolamento galvanico. Possono essere di tipo regolato, per stabilizzare la tensione di uscita, o non regolato, in cui quest’ultima è direttamente proporzionale alla tensione di ingresso per il rapporto di trasformazione.
