“…Each switch is turned on with other staying off to generate the AC output by charging and discharging the passive components. The usage rate of the PV arrays could be increased to as high as 96% by varying the capacitor connected with the PV arrays [3]. Due to the high switching frequency (9.6kHz) in hard switching mode, the overall efficiency which reaches at 82% at 400W is not desirable which still need to be improved.…”

As demand for green power and off-grid applications increase, distributed generators are becoming more commonplace. The range of power and voltage output rating are greatly extended with careful use of semiconductor devices employing appropriate soft switching techniques. This paper presents a review of the inverter topologies for single and multi-stage conversion and gives a classification according to power, input voltage rating and operating efficiency. The "trade-offs" required for high efficiency design are identified for each of the published circuits and the discussion of losses in both hard and soft switching topologies is given. The selection of soft switching topologies based on design requirement is discussed and efficiencies for various multi-stage inverters are provided. Final recommendations are offered for choosing optimum topologies based on the specific design parameters.

“…But DC voltage which is produced by solar panels will changes as the change of light intensity, angles, and it is very unstable. [7] [8] New-style z-source inverter can be used to solve this problem and makes bus-voltage of lighting system constant. Polycrystalline silicon solar panels that install on the surface of ship convert light energy into electricity by absorbing infrared and visible light.…”

The traditional z-source has some flaws such as higher capacitor voltage, larger startup surge current and so on when it works, while, the new-style z-source has some strong points such as lower capacitor voltage, adopting appropriate soft-start strategy to limit surge current, reducing the current stress or the voltage stress of the switch components, low implementation cost, etc. The article has discussed the development of the digital controlling new-style z-source voltage-source inverter which applies to photovoltaic lighting system of ship. For making the DC link voltage of z-source inverter constantly, voltage feedforward and feedback control method is introduced in z-source inverter system. the SPWM modulation method is introduced in the inverter, and the appropriate strategy of soft-start is taken to reduce surge current in starting. The results of experiment show that the voltage stress of component is low, startup surge current is low, the output voltage is stable and the device works reliable, it achieves satisfactory effect.

“…The aforementioned topologies cannot meet this requirement; therefore, an isolated converter must be added in the front stage, which greatly increases the system complexity and cost. An inverter topology with an inherent common ground for input and output was proposed for grid-connected application in [3], but it requires a split dc input voltage source and four switches.…”

This paper proposes a novel single-phase Z-source inverter topology with input and output sharing the same ground. It is simple in structure and only utilizes two switches while keeping the voltage transfer ratio the same as for the full-bridge inverter. One-cycle control is adopted. Highly efficient constant-frequency control can be achieved without an accurate model of the converter. The unique feature of the proposed topology is verified by operating principle, simulation and experimental results. This topology can be used in distributed power systems where dual grounding is needed.Index Terms-One-cycle control, single phase, Z-source inverter.
