“…There are topologies in which the zero ripple cancelation point can be selected (flexible) [7,8,9,10], and they can be done with commercial devices, but they cannot be done with commercial converters. Using commercial converters instead of customized to achieve the discussed challenge can expedite the design process and reduce the cost, which is highly desirable.…”

Interleaved switching converters are used in several applications such as power source for a PC microprocessor, one of their advantages is the capability to cancel a portion of the current ripple generated by the switching action, in the output for a buck case and in the input for a boost case. Depending to the voltage gain the operate, that current ripple can be equal to zero. Interleaving connections are made with converters of the same topology, this work explores the interleaving connection of unequal topologies Boost and Cuk, the objective is to develop an interleaving boost topology to reduce the total harmonic distortion at the input current in the full operating range, the input current ripple represents the power quality of switching mode power supplies from the input source point of view. The combined converter achieves a larger voltage gain compared with the traditional boost converter but their main advantage is the extra degree of freedom on reducing the input current ripple for certain operating conditions. Experimental results are provided to verify the theoretical analysis and prof the principle of operation.

“…Unfortunately, multiple complications exist with such energy sources: for example, fuel cells and photovoltaic modules cannot accept currents in the reverse direction, do not perform well with current ripples, and have low voltage characteristics [1][2][3][4][5][6][7][8][9][10][11]. For these reasons, normally a boost converter is required to step-up and regulate the input voltage to a higher value [3,4,[6][7][8][9][10][11]. However, the inherent inductor current ripple of the boost converter causes a high frequency input in the current ripple [6,7,9].…”

Abstract:In this paper, in order to achieve zero ripple conditions, the use of a ripple mirror (RM) circuit for the boost converter is proposed. The operation modes are studied and steady-state analyses performed to show the merits of the proposed converter. It is found that the proposed RM circuit technique can provide much better flexibility than the two-phase interleaved boost converter for locating the zero ripple operating point in the design stage. In addition, the choice of using a boundary-mode control is mainly based on the consideration of achieving both ZVS (zero voltage switching)/ZCS (zero current switching) soft-switching and constant on-time control for the converter. To verify the performance of the proposed converter, a 48 V input and 200 W/200 V output prototype is constructed. Experimental results verify the effectiveness of the proposed converter.

Available online xxxKeywords: PEMFC Interleaved DC/DC converter Electric vehicle Power switch fault Fault-tolerant control Degraded operating mode a b s t r a c t In recent years, the effects of high-frequency current ripple coming from DC/DC converters on Proton Exchange Membrane Fuel Cell (PEMFC) have gained a growing interest from the international scientific community. Currently, the durability is one of the major technical challenges to PEMFC commercialization. Basing on the existing literature, the highfrequency current ripple leads up to long-term degradations on PEMFC, particularly on its lifetime. Accordingly, in order to enhance the PEMFC lifetime, new DC/DC converter topologies have been developed, such as Interleaved DC/DC Boost Converter (IBC). Despite this topology can minimize drastically the current ripple, the loss of one leg in case of power switch fault leads up to the drastic increasing of the current ripple and consequently long-term degradations on the PEMFC. In order to cope with this issue, solutions have to be developed. Within the framework of this research work, an efficient Fault-Tolerant Control (FTC) implemented on an FPGA board has been developed to solve this issue. The latter consists in changing the PWM gate control signal according to the faulty leg given by a fault detection algorithm. The obtained experimental results between a PEMFC and an IBC topology allows demonstrating the ability of the FTC to reduce drastically the current ripple in case of power switch faults.
