Interleaved dual Boost-type DC/DC converter

An interleaved dual Boost-type DC/DC converter is proposed, and the phase difference of driving signals between corresponding switches is 180°. Its six switching states within a switching period are introduced with the variation of main voltages and currents and its characteristics are analyzed in detail. The experimental results demonstrate the followings: its control is simple and reliable; the control ICs are off-the -shelf; soft-switching is applicable to all active or inactive switches; the voltage and current stresses of switches are not increased; compared with the traditional Boost-type DC/DC converter, the input inductor and output capacitor are reduced when the input and output conditions are the same, because the equivalent frequency of input inductive current or output voltage ripple is the double of the switching frequency.
