چکیده
Abstract: This paper presents a recent popular power inverter which is impedance source or Z-source inverter (ZSI) and the comparison and analysis of two conventional PWM techniques of Z-source inverter. Due to the impedance network it couples inverter main circuit to the power source thus providing special features that can overcome the limitations of traditional voltage source inverter (VSI) and current source inverter(CSI).In this paper we discussed and analyzed about the different conventional PWM techniques like Simple Boost Control, Maximum Boost Control, Maximum Boost Control with third harmonic injection, Maximum Boost Control with triplen injection where it is observed that the Maximum Boost Control with triplen injection is much better than other techniques in respect of load current ripple, inductor current ripple and capacitor voltage ripple for different modulation index and same switching frequency.
