Abstract: Power electronic converters are used for conversion of power from either AC to DC or DC to AC. Inverters convert DC power to AC power. A voltage source inverter (VSI) has been in use for power inversion but it suffers from few disadvantages. One of those drawbacks is, a VSI works as a buck converter only. So, in VSI, it is not possible to get an output which is more than the given input. To overcome this drawback, in this paper, Impedance source Inverter (ZSI) is presented. This inverter behaves as buck-boost inverter,i.e., using this inverter, we can get output either more or less than the given input. The PWM technique used to control the inverter is the proposed Unipolar PWM technique.
