| description | This paper introduces a new cost effective structure of a 4-switch single-phase to three-phase converter using a Quasi Z-source (QZs) network for induction motor drive applications. In comparison to the traditional 6-switch structure, the proposed circuit reduces the cost of the system, switching losses and the complexity of the control method as well as the interface circuits used to make the trigger signals. In addition, The Quasi Z-Source network, similar to the Z-Source network uses a unique LC network with added advantages, such as; lower component ratings, reduced source stress, reduced component count and simplified control strategies for Adjustable Motor Drives (ASD) which require large range of gain. By controlling the zero shoot-through duty cycle, the converter can generate any desired output voltage, even greater than the supply voltage. Consequently, the converter is capable of extending the output voltage range, improving the power factor and reliability, reduces line harmonics and provides ride-through ability at the voltage sag interval. Simulation results on the proposed converter have indicated its efficiency and potential for further development. |
