چکیده

This paper presents an alternative power conversion topology that can buck or boost the input voltage/current with linear and non-linear load depending upon duty ratio and modulation index in a single stage conversion with the help of Impedance source passive Network (L and C), which is usually known as Z-Source. The buck and boost capabilities of inverters are operated in the shoot through state. The objective of this Paper is to demonstrate a low-cost, efficient, and reliable inverter for linear and non-linear load. This paper verified the simulation result for Z-Source PWM inverter with MATLAB and implementation to any linear and nonlinear three phase load. The unique feature of Z-Source network is shoot-through duty cycle and it acts as a filter which reduces the line harmonics, improves power factor, increases reliability and extends the output AC voltage range of inverter.
