In this paper, a backstepping control combined with a modified space vector modulation (MSVM) for a quasi z-source inverter (QZSI) fed by a fuel cell is proposed. The QZSI employs a unique impedance network to couple the main circuit of the inverter to a proton exchange membrane fuel cell (PEMFC). This topology provides an attractive single stage DC-AC conversion with buck-boost capability unlike the traditional voltage source inverter (VSI). The MSVM is used to insert the shoot through state within the traditional switching signals in order to boost the inverter input voltage, and to keep the same performances of the traditional SVM. A DC peak voltage controller using backstepping approach is proposed to overcome the fuel cell voltage fluctuations under load changes, and to reduce the inductor current ripples as well. Comprehensive simulations are presented to prove the effectiveness and the performances of the proposed control strategy under different operating conditions.

“…In general, there are 2 states in a complete qZSI operating period T s , as shown in Figure 2. 17,[28][29][30] Figure 2A is the operation of the STS, in which the switches in 1 bridge leg must be turned on at least. Another, as shown in Figure 2B, is the equivalent circuit of the non-STS operation, where the qZSI works as a conventional inverter.…”

“…Recently, the quasi-ZSI (qZSI) has been extensively researched as an up-to-date PCU configuration for applications in renewable and alternative energy sources. [12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27] The qZSI inherits all the advantages of the ZSI. In addition, the qZSI has the saliently attractive characteristics, such as lower component stresses and switching ripple to PV panel, a continuous current drawing from the PV source thus extra filtering capacitors can be saved, and a common dc rail between the source and inverter.…”

In this paper, a single-phase quasi-Z-source (qZS) inverter (qZSI), integrating the pulse width modulation (PWM) control with interleaved-and-shifted shoot-through state (STS) placement modulation technique, is proposed to simultaneously achieve both dc voltage boost and dc-ac inversion. Instead of placing the STS in both inverter legs simultaneously, the addressed method inserts the STS only in left/right inverter leg separately during the positive/negative half cycle of the output voltage to reduce switching losses and thermal stresses of the power devices. The STS shift is also studied to decrease the switching numbers of power devices and thus can improve the efficiency further. Theoretical analysis and design guidelines of the studied inverter are included. Improvement in effectiveness and performance of the devised scheme and modulation strategy are proved experimentally and compared with the previous studies on a built laboratory prototype.

In Battiston et al , 6 an improved flatness control strategy for a quasi-Z-source inverter fed permanent magnet synchronous motor operated EV has been presented to improve the efficiency of the direct current (DC)-alternating current (AC) converter. The flatness controller offers good robustness and high dynamic performance.…”

This paper presents a high gain modified three-port dual boost single-ended primary-inductor converter (SEPIC) converter operated hybrid photovoltaic (PV)/battery electric vehicle to improve the power transfer capability and efficiency of the power conversion stage. The proposed three-port dual boost high gain SEPIC converter accepts wide voltage range of input then the conventional single stage SEPIC converter. The three-winding high frequency coupling transformer integrates the two input sources and step-up the input voltage. The theoretical and experimental analyses are presented to validate the performance of the proposed modified SEPIC converter in boosting the wide range of input voltage. A 6 kW, 12 to 600 V of experimental model has been developed and tested. The efficiency obtained from the designed model is around 94.11%.
