“…Estos se calculan en función de la respuesta y dinámica deseada, con esto se obtiene el ciclo de trabajo (D) que ingresa al modulador [22]. Cuando se trabaja con en el método directo, se utiliza el pico de voltaje de salida de la red de impedancia y se aplica el mismo procedimiento descrito anteriormente, es decir obtener la función de transferencia y un controlador PI el cual ahora regula el índice de modulación (M) [18]. Por lo general cuando se diseñan sistemas con regeneración o bidireccionales se considera la corriente de carga como una variable de estado más, esto permite disminuir las pertubaciones en la tensión de entrada así como las oscilaciones del controlador [7].…”

“…[34] The single-loop control has feedback from the dc source voltage Vin [22], capacitor voltage vc [24], [34], or the dc-link voltage vdc [25], [28], then the command shoot-through duty ratio D is generated. It is noted that the dc-link voltage of ZSI is pulse voltage waveform due to shoot-through zero states, which is not suitable for direct utilization as feedback variable.…”

“…More recently, various studies of voltage-fed ZSIs/qZSIs have been devoted in 1) their derived topologies to improve the voltage gain of the basic ZSI/qZSI [6]- [12]; 2) Z-source pulsewidth modulations (PWMs) to achieve buck/boost [13]- [21]; 3) feedback control and parameter design by statespace averaging or dynamic modeling [22]- [33]; 4) applications, such as traction drive [34]- [36], wind [37]- [39], and PV power conversions [40]- [42]; and 5) combinations with traditional power conversion techniques, e.g., integrating with energy storage batteries (ESBs) [43]- [49], coupling into the conventional matrix converter [50]- [52], neutral-point-clamped inverter [53]- [55], and cascade multilevel inverter (CMI) [56]- [63], etc. Studies also carried out current-fed ZSI/qZSI [64]- [66] and ZS/qZS dc-dc converters [67]- [72].…”

T he current and emerging investigations on Z-source/quasi-Zsource inverters (ZSIs/qZSIs) are presented. The ZSI/qZSI fulfills buck/boost capability in single-stage topology and overcomes the limits of traditional voltage source inverters (VSIs). Hence, high reliablity, high efficiency, and low cost can be achieved. The recently derived impedance networks with improved voltage gain are discussed. The classic and newly proposed modulations and feedback controls for ZSIs/qZSIs are compared. Finally, the emerging applications and trends of ZSIs/qZSIs to photovoltaic (PV) power generation are discussed. This study offers a comprehensive and systematic reference for the future development of the high-performance ZSI/qZSI.The ZSI [1] and qZSI [2] were proposed in 2003 and 2008, respectively, to overcome the barriers of traditional two-level VSIs and current source inverters (CSIs). Traditional VSIs have to perform dead time between the upper and lower switches in one bridge leg to avoid short circuit, which introduces ac output waveform distortions. On the other hand, an extra dc-dc boost converter is usually required

Abstract-In a Grid connected three-phase photovoltaic (PV) system, there is double-frequency power mismatch existed between the dc input and ac output. The double-frequency ripple (DFR) energy needs to be buffered by passive network. Otherwise, the ripple energy will flow into the input side and adversely affect the PV energy harvest. In a conventional PV system, electrolytic capacitors are usually used for this purpose due to their high capacitance. However, electrolytic capacitors are considered to be one of the most failure prone components in a PV inverter. In this project, a capacitance reduction control strategy is proposed to buffer the DFR energy in three-phase Z-source/quasi-Z-source inverter applications. Without using any extra hardware components, the proposed control strategy can significantly reduce the capacitance requirement and achieve low input voltage DFR. Consequently, highly reliable film capacitors can be used. The increased switching device voltage stress and power loss due to the proposed control strategy will also be discussed. The proposed system is simulated in MATLAB/Simulink platform.Index Terms-DC-link voltage balance, Zero voltage switching, Renewable Energy (RE).
