Interleaved Boost Converter with ZVT-ZCT for the Main Switches and ZCS for the Auxiliary Switch
Source abstract
Abstract
A soft-switching interleaved topology is presented herein and applied to the boost converter. The basic operating principle is that the main power switches are turned on at zero voltage and turned off at zero current via the same auxiliary resonant circuit whose switch is turned on from zero current. Furthermore, as compared to the traditional boost converter, the proposed topology has three additional auxiliary diodes, two additional auxiliary capacitors, one additional auxiliary inductor, and one additional auxiliary switch. On the other hand, since the interleaved control is adopted herein, the difference in current between the two phases exists. Hence, the cascaded control is utilized to regulate the output voltage to the desired voltage via the first phase, whereas the current-sharing control, based on half of the input current as the current reference for the second phase, is employed so as to make the load current extracted from the two phases as evenly as possible. In this paper, the effectiveness of the proposed topology and control strategy is demonstrated by some experimental results.
