To achieve high-power density in
power supplies, it is desirable to minimize the physical size of the energy
storage capacitor. The capacitance is determined by the energy storage
requirement for line outage ride-through and also the ripple current handling capability
of the capacitor. Interleaving is well known as an effective method to reduce
the capacitor ripple current and in cases where ripple current considerations
dominate, it could reduce capacitor size. High frequency operation of
converters results in high switching losses. Several soft-switching techniques
have been proposed in recent literatures to substantially reduce the switching
loss. In this paper, a soft-switching interleaved boost converter composed of
two shunted elementary boost conversion units and an auxiliary inductor is
proposed. Simulation results reveal that the performance of this proposed
converter is better than that of conventional boost converter.
