Abstract
In this paper, a new non-isolated DC-DC converter is proposed. This converter topology is a high step-up boost converter with an extended voltage multiplier cell and a Cuk converter as a series output module. Compared to its high step-up counterpart, the proposed converter has a higher voltage gain. In this converter, an active clamp circuit is used to absorb the energy of leakage inductor, therefore, the ZVS turn on/off for switches and ZCS for diodes are achieved. The voltage stresses on the switches are low, and the reverse-recovery problem of the diodes is eliminated. The operational principle and characteristics of the proposed converter are presented. The analytical and simulated results are validated using a 200 W prototype converter with 20 V input and 400 V output operating at 100 kH.
