Title
A Family of Module-Integrated High Step-Up Converters With Dual Coupled Inductors.
Abstract
In order to overcome the defect of low output voltage of the renewable energy-based generators, such as the photovoltaic array and fuel cells, a family of high step-up integrated dc/dc converters with dual coupled inductors is proposed based on combination of the modified quadratic boost converters and the voltage-multiplier modules (VMM). The high voltage gain can be achieved by adjusting the duty cycle and turn ratios of the coupled inductor of VMM. In particular, quite low voltage stress on the power switch can be obtained since the switch is no longer directly excited by the high output voltage, which is useful for enlarging the power efficiency. In addition, the two inductors in MQBC are integrated by using one magnetic core to decrease the size of the magnetic components. Very small ripples of the input current can be realized by ripple suppress abilities of the coupled inductors. Two experimental prototypes with rated-power of 200W are selectively constructed for comparative analysis, and experimental results verify the correctness and practicability of the proposed converters.
