In this paper literature review of PV module integrated converters has been conducted. Many times it is necessary to boost the PV voltage, further the size of power processing circuitry should be as small as possible. Considering this many researchers have worked on development of module integrated converters, in which converters are fitted in PV module. The PV output is boosted to desire level by using suitable MPPT techniques. Converters with high efficiency, higher voltage gain, and cascaded topologies can be designed for this purpose.

This paper presents a novel DC-AC inverter based on a high frequency power electronic transformer. It makes use of an adapted push-pull converter on the primary side of the transformer to apply a high frequency alternating voltage. This keeps the transformer flux low and transformer size small, reducing the cost of materials but at the same time keeping the power density high. The secondary side is a set of two bi-directional switches that synthesize the desired output voltage in a cycloconverter manner, helping to reduce the total harmonic distortion. A state space control strategy and commutation of the secondary side is also presented. The topology and control strategy has been confirmed with simulation results.

“…Low and high frequency components of currents reduce the PEMFC output power and decrease the durability of the membranes [9]. To improve the lifespan of PEMFCs, many solutions were proposed to reduce the ripple and harmonic components of the current, as reported in [10][11][12]. One of the various proposed power converters is the multiphasing or interleaved DC-DC boost converter [13].…”

This paper presents a simple strategy for controlling an interleaved boost converter that is used to reduce the current fluctuations in proton exchange membrane fuel cells, with high impact on the fuel cell lifetime. To keep the output voltage at the desired reference value under the strong fluctuations of the fuel flow rate, fuel supply pressure, and temperature, a neural network controller is developed and implemented using Matlab-Simulink (R2012b, MathWorks limited, London, UK). The advantage of this controller resides in its simplicity, where limited number of tests are carried out using Matlab-Simulink to construct it. To investigate the robustness of the proposed converter and the neural network controller, strong variations of the fuel flow rate, fuel supply pressure, temperature and air supply pressure are applied to both the fuel cell and the neural network controller of the converter. The simulation results show the effectiveness and the robustness of the both the proposed controller and converter to control the load voltage and minimize the current and voltage ripples. As a result of that, fuel cell current oscillations are considerably reduced on the one hand, while on the other hand, the load voltage is stabilized during transient variations of the fuel cell inputs.
