Abstract
The recently developed, emerging Z-source inverter topologies are well suitable for Power Conditioning System (PCS).This paper presents the effective performance analysis of three different voltage type Impedance Source Inverter (ZSI) topologies such as classical ZSI, improved Z-source inverter and embedded Z-source inverter with four control techniques, namely Simple Boost Control (SBC), Maximum Constant Boost Control (MCBC), Maximum Constant Boost with Third Harmonic Injection and Modified SVPWM for Power Conditioning System. ZSI family is a single stage high efficiency power converter that eliminates almost all the limitations of traditional inverters such as Voltage Source Inverter (VSI) and Current Source Inverter (CSI). Performance analysis is carried out based on the obtainable impedance source capacitor voltage, inductor current ripples, DC link voltage ripples, peak output voltage, output phase current harmonics and effectiveness of the control methods for battery powered applications.
