Abstract :
A new serial fix type switched-capacitor (SC) transformers is presented, whose input current ripple becomes almost zero. By using two voltage averaging capacitors, low ripple characteristics are realized. In this circuit, the number of the serial connected capacitors does not increase and the condition to decrease the ripple is not strict
