A novel DC-DC converter circuit whose step-up ratio is much larger than that of the conventional boost converter is presented in this paper. It also describes that the circuit can be modified to a bi-directional one with larger step-up and step-down ratios. These features can be obtained by charging two capacitors in parallel and discharging in series or vice versa alternately. The circuit is simple and has some significant advantages like extended output voltage, less input current ripple and output voltage ripple over the conventional converters. Hence, it may find good applications to household UPSs and power conditioners for fuel cell systems.
