This paper proposes a soft-switching interleaved boost converter which is suitable for high step-up and high power applications.
Compared to the conventional boost converter the proposed converter can achieve approximately doubled voltage gain using the
same duty cycle. The voltage ratings of the switch and diode are reduced to half, which result in the use of devices with lower RDS(ON)
and on drop leading to reduced conduction losses. Also, voltage ratings of the passive components are reduced, and therefore the
total energy volume is reduced to half. Further, the switch is turned on with ZVS in the CCM operation, and the diode is turned off
with ZCS which results in negligible surge caused by diode reverse recovery leading to reduced switching losses. The validity of the
proposed converter is proved through a 2kW prototype.
