The advantages, limitations and disadvantages of Z-source inverter

A Z-source converter is an unique x-shaped impedance network called Z-source impedance network that couples the converter main circuit to the power source. The converter may be of all conversion types - if it is of ac-to-dc type, the z-source converter is called z-source inverter. Since 2003 when this recently conversion concept appeared, it proved able to solve many conversion problems. In this paper it's superiority compared to traditional solutions are shown. There are also small disadvantages and limitations revealed.
