“…To further investigate the difference among the three methods on output voltage harmonics, open-loop simulations have been conducted with M=0.9 and B=0. 25 such that the magnitude of modified modulation waves would go beyond the magnitude of the carrier wave and the output harmonics would increase undoubtedly. In this way, the effect of the three control methods on output harmonics could be clearly illustrated.…”

“…Besides the basic Z-source impedance topology, many modified Z-source topologies have been developed [22]- [24] to reduce switching loss and improve power density. Though these proposed converters based on Z-source topology could generally achieve smaller size and wider voltage conversion ratio, they have issues in complicated structure, instability, voltage stress of switches, power level limitation [24] and output harmonics [7] [25]. Therefore, this paper aims to improve the performance of converter by designing and optimizing the control method of a basic three-phase Z-source converter, rather than adding more devices or complicated circuits.…”

Three-phase Z-source inverters provide a solution of voltage boosting by a single-stage topology. They are also capable of bi-directional operation as rectifiers, thus have great potential for applications in the field of transportation electrification such as Vehicle-to-Grid (V2G) chargers. In this paper, three new modulation schemes for three-phase Z-source converters are proposed and investigated. The best performed one is further developed to a closed-loop PI control method. While the voltage conversion ratio is flexible, the output voltage Total Harmonics Distortion (THD) is below 3% within the voltage ratio range of 0.5 to 2.5. The effectiveness of the proposed method has been fully validated in MATLAB/Simulink simulations and RT-LAB Hardware-In-Loop (HIL) experiments based on the realtime simulator OPAL-RT OP4510. Compared to existing control methods, the proposed one performs better with reduced harmonics, flexible voltage gain, and simpler control algorithm.

“…Due to these interesting features, many research works are intended for applying the ZSNs to DC-AC power conversion applications with novel control algorithms and modulation schemes [3][4][5]. They are also adopted to DC-DC [6][7][8], AC-DC [9] and AC-AC [10] power converters. The flexibility of ZSNs for employing in many types of power converters is investigated in [11].…”

This paper proposes a new enhanced-boost non-transformer-based impedance source network. The strong boosting ability of the proposed topology is realized by making use of the switched capacitor concept in the formerly introduced enhanced-boost quasi Z-source network (EB-qZSN) without any additional active switch. Meanwhile, the advantages of the EB-qZSN such as input current continuity and shared ground between the input and the output are maintained. In addition to the lower shoot-through requirement to obtain high voltage gains, the proposed impedance network takes advantage of a smaller size of passive components along with a lower input current ripple to achieve higher power density and higher efficiency. Moreover, the lower total rating of the switching elements, defined by switching device power, directly translates to lower cost for the proposed method. The operation principles and the design guideline of components are explained in detail and a thorough comparison with other ZSN is presented. A 240W DC-DC prototype converter was built to validate the performance principles and properties of the proposed impedance network.

This paper proposes a series of new control methods for single-phase Z-source inverters. A detailed description of the concept and principle of each method is first presented, then a comparison among them is conducted comprehensively. Afterwards, an optimized closed-loop control scheme with better harmonic elimination performance is derived. Experimental results obtained from a 1kW un-isolated Zsource inverter prototype have demonstrated the effectiveness of the proposed control method. Compared to the conventional boost control, the proposed scheme has better performance with reduced harmonics, more flexible voltage gain, and simple algorithm. INDEX TERMS Z-source inverters, shoot-through states, closed-loop control, harmonics suppression, voltage boosting.
