All of the structures that have been presented in [25][26][27][28][29][30][31][32][33][34][35][36] are the switched boost inverters with a voltage source. In [33,34], the dual of these structures with the current source has been presented and they increase the current level and are immune from an open circuit.…”

This study reviews and categorises different structures of switched Z-source networks. Generally, these structures are divided into two groups of basic switched Z-source networks and switched Z-source networks with the capability of high boost. Each of these groups is divided into several subgroups and different structures are introduced. For each subsection, the general power circuit is proposed and the extraction method from general power circuit for each structure is obtained. This study also provides a complete analysis of structures by using a conventional control method with two shoot-through and non-shootthrough modes. Small signal analysis for structures with a basic switched Z-source network is conducted and the general signal flow graph is extracted. A comprehensive analysis of all structures with a switched Z-source network is done and the tree diagram for the division of these structures is provided. Finally, different industrial applications and outlook of Z-source networks are introduced.

“…Switched Boost Inverter (SBI) is a single stage power converter derived from Inverse Watkins Johnson (IWJ) Topology [4]- [5]. Similar to a Z-Source Inverter (ZSI) [8], the SBI also utilizes the shoot-through state of the inverter bridge (both switches in one leg of the inverter are turned on simultaneously) to generate an ac output voltage higher than the available dc source voltage.…”

Switched boost inverter (SBI) is a single stage power converter that can supply both dc and ac loads simultaneously. Unlike the traditional buck type voltage source inverter (VSI), the SBI can produce an ac output voltage that is either greater or less than the available dc input voltage. Also, the SBI exhibits better EMI noise immunity when compared to the VSI. These features make the SBI suitable for microgrid and nanogrid applications. In this paper, the SBI is proposed as a power electronic interface in DC nanogrid. The structure and advantages of the proposed SBI based DC nanogrid are discussed in detail. A closed loop control system is also designed for the SBI supplying both DC and AC loads using Synchronous Reference Frame (SRF) approach, and it is implemented in digital domain using Texas Instruments TMS320F28335 Digital Signal Processor (DSP). The control system of SBI has been experimentally validated using a 0.5 kW experimental prototype of SBI supplying both DC and AC loads, and the relevant experimental results are presented in the paper. The experimental results show that the DSP based control system shows excellent performance under the steady state as well as during the transients in either DC or AC loads in the system. The low cross regulation of the control system has also been verified for a step change in either DC or AC load of SBI. These experimental results confirm the suitability of the SBI and its closed loop control strategy for DC nanogrid applications.I.
