Abstract
An interleaved quadratic boost converter
integrated with capacitive voltage multiplier is proposed in
this paper. Two quadratic boost switching cells are
interleaved to minimize the current ripples in input side. Its
output is coupled to a voltage multiplier to increase the
static gain, resulting in a higher output voltage with
moderate duty cycle. Compared with the conventional boost
converter and quadratic boost converter, the proposed
converter has reduced voltage stress in the switches and
diodes. The detailed analysis of the converter is presented
for both continuous. A prototype is simulated and
implemented in the laboratory. The results validate the
theoretical analysis and confirm the viability and significant
performance of the converter. The maximum efficiency of the
proposed converter is 91.5 % under full load.
