N2 - This paper deals with a new family of single-phase impedance source ac-ac converters which employs a high frequency transformer between the impedance source network and the load. The proposed structure have unique features: providing a wide range of output ac voltage with buck-boost, maintaining or reversing the phase angle, and reduced inrush and harmonic current component. In addition to the aforementioned benefits the proposed converter incorporates a high frequency transformer which provides isolation between input and output, and removes the need for bulky 60 Hz low frequency transformer which improves the efficiency of the converter in terms of size, weight and cost of the transformer. Moreover, high frequency transformer can also be utilized in adjusting the gain of the converter. An experimental prototype of proposed converter is built and tested to prove its performance and effectiveness.
