Comparison of Traditional Inverters with ZSI and Simulation of Maximum Boost Control Method of ZSI

In this paper, two traditional inverters (Voltage source inverter & Current source inverter) are compared with newly introduced Zero Source Inverter (Zsi).As per the topology of Converters, Voltage source converter has a capability of increasing the output as per requirement of condition and it works as a boost converter. Also voltage source inverter has a capability of step-down the output and works as a buck inverter. On other hand, Opposite to the voltage source converter topologies, current source converter has a capability of step-down the output and works as a buck converter. Where Current source inverter has a capability that it can be increasing the output as per requirement. This newly introduced design which is Zero source converter design has a capability of both voltage source and current source converter. That mean, it can be step up and step down the output as per design consideration and requirement and providing unique features that cannot be obtained in the traditional voltage-source(or voltage-fed) and current-source (or current-fed) inverters where a capacitor and inductor are used, respectively In traditional voltage source converter and current source converter a capacitor and inductor are used respectively. But in ZSI, both capacitor and inductor are used for Buck and Boost process. The Z Source converter overcomes the conceptual and theoretical barriers and limitations of Traditional voltage source and current source converter. The Z-Source concept can be applied to all DC-TO-AC, AC-TO-DC, AC-TO-AC, DC-TO-DC power conversion. This paper describes Inverter mode of voltage source converter, current source converter and Zero source converter. Also the comparison of three of them. There are three control modes of ZSI out of which analysis and simulation of Simple boost control method of ZSI is demonstrated in this paper.
