Abstract：This paper mainly develops a novel topology，which is called quasi-Z-source inverter（QZSI），derived from the traditional
Z-source inverter（ZSI）.The equivalent circuit and operating principle analysis are given and the space-vector PWM
technique is applied into single phase QZSI（spQZSI），the basic modulation principle and control strategy of spQZSI based
SVPWM are showed.The simulation and experimental results indicate the presented QZSI has merits of suppress the inrush
current and remarkable lower component voltage ratings，thus save the entirety costs and strength the system reliabilities.

Description: This code presents a single-phase, single-stage
current source inverter (CSI) based photovoltaic system (PV)
for grid connection. A double-tuned parallel resonant circuit is
designed to attenuate the second- and fourth- order harmonics
at the inverter dc side. It helps to improve the power quality and
system efficiency. A modified carrier based modulation
technique for the current source inverter is studied to magnetize
the dc-link inductor and to control the switching pattern for the
single phase grid-connected CSI. The operation of Single Phase
Transformer-less grid connected PV system is verified by the
simulation using MATLAB/Simulink software. The results are
analyzed and presented. Platform: |
