Current-fed double inductor push-pull DC/DC converter with closed loop control system

چکیده
In order to use hydrogen fuel cells in domestic applications either as main power supply or backup source, their low DC output voltage has to be matched to the level and frequency of the utility grid AC voltage. Such power converter systems usually consist of a DC-DC converter and a DCAC inverter. A double inductor step-up push-pull converter with the output voltage and the input current control is investigated in this paper, presenting simulation and experimental results for passive and active overvoltage clamping. The prototype of the investigated converter is elaborated for 1200 W power to match the rated power of the proton exchange membrane (PEM) fuel cell located in hydrogen fuel cell research laboratory.

A Three-Phase Current-Fed Push–Pull DC–DC Converter
In this paper, a new three-phase current-fed push– pull dc–dc converter is proposed. This converter uses a highfrequency three-phase transformer that provides galvanic isolation between the power source and the load. The three active switches are connected to the same reference, which simplifies the gate drive circuitry. Reduction of the input current ripple and the output voltage ripple is ach...
