A Three-State Switching Boost Converter Mixed With Magnetic Coupling and Voltage Multiplier Techniques for High Gain Conversion

ABSTRACT:

An asymmetrical 3-state switching boost converter, combining the benefits of magnetic coupling and voltage multiplier techniques, is presented in this paper. The derivation procedure for the proposed topology is depicted. The new converter can achieve a terribly high-voltage gain and a very low-voltage stress on the facility devices while not high turn ratio and extreme duty cycles. Therefore, the low-voltage-rated MOSFETs with low resistance rDS (ON) will be selected to reduce the switching losses and cost. Moreover, the usage of voltage multiplier technique not solely raises the voltage gain however additionally offers lossless passive clamp performance, thus the voltage spikes across the most switches are alleviated and therefore the leakage-inductor energy of the coupled inductors can be recycled. Additionally, the interleaved structure is employed within the input facet, that not solely reduces the current stress through each power switch, however conjointly constrains the input current ripple. Additionally, the reverse-recovery drawback of the diodes is alleviated, and therefore the efficiency will be further improved. The operating principles and also the steady-state analysis of the presented converter are discussed very well. Finally, a prototype circuit with four hundred-W nominal rating is implemented in the laboratory to verify the performance of the proposed converter.
