“…Up to the present, there have been many methods to realize high step-up converters. For example, the literatures [1][2][3][4][5][6][7][8][9] take the coupling inductor methods or the charge pump methods; the literatures [10][11][12][13][14] adopt the energy superposition or even combine the methods mentioned above. However, the literatures [15][16][17][18][19][20][21][22][23][24][25][26][27] have individual demerits.…”

A photovoltaic energy conversion system, constructed by high step-up converter with hybrid maximum power point tracking (HMPPT), is presented. A voltage converter with a high voltage conversion ratio is proposed, which is simple in circuit and easy in control. After this, such a converter operating with a suitable initial duty cycle of the pulsewidth-modulated (PWM) control signal, together with the proposed HMPPT algorithm combining the fractional open-circuit voltage method and the incremental conductance method, is applied to the photovoltaic energy conversion system. By doing so, not only the maximum power point tracking speed can be increased, but also the oscillation around the maximum power point can be reduced. Aside from these, the field programmable gate array (FPGA) is used as a control kernal of the overall system, so as to realize the HMPPT and fully digitalized control. Finally, via a PV simulator, some experimental results are provided to verify the effectiveness of the proposed photovoltaic energy conversion system.

“…Voltage gain can be increased effectively by introducing a coupled inductor, but the leakage inductance may cause high-voltage spikes on the switch when it turns off. Various passive or active auxiliary circuits have been proposed to absorb the energy which is stored in the leakage inductance [7][8][9]. In such cases, the whole circuit may turn out to be more complex and less efficient.…”

This study proposes a kind of high step-up dc/dc converter with a novel voltage multiplier cell (VMC). The proposed VMC sharply reduces voltage stress on switches and diodes. Therefore, the conversion efficiency can be improved significantly. The converter also provides a wide range of voltage conversion ratios including fractional as well as VMC numbers and switch duty cycle. The topologies, operation principles, working characteristics and voltage conversion ratio are analysed in detail. A 500 W experimental prototype with two VMCs has been developed to validate the effectiveness of the theoretical analysis, and the highest efficiency is 93.8%.

“…The study of the application of intercell transformers (ICTs) in interleaved converters has attracted the interest of researchers in the latter years [1][2][3][4][5]. This is due to the real gain obtained in terms of volume reduction by coupling the paralleled modules instead of using separated inductors [6].…”

Recent works of different authors have shown that the use of intercell transformers in interleaved inverters bring many improvements to this kind of parallelism. However, even though a balanced current distribution is necessary and not guaranteed by the converter itself; just a few of those studies are focused on the modelling and control of the inverter. Moreover, the fact that the paralleled modules are coupled and that the control signals are not updated simultaneously have not been considered yet. In this way, the current paper takes those facts into account and proposes a simple procedure for modelling and control a single-phase interleaved inverter. A mathematical analysis, some simulation and experimental results are shown in order to prove the simplicity and effectiveness of the proposed procedure.
