《Applied Numerical Methods Using MATLAB》是Wiley出版社2005年出版的书，是Matlab应用在数值运算和机器学习领域最权威的书。("Applied Numerical Methods Using MATLAB" is published by Wiley in 2005. It is the most authoritative book used in Matlab numerical computing and machine learning.)

This paper proposes an improved Z-source inverter topology. Compared to the traditional Z-source inverter, it can reduce the Z-source capacitor voltage stress significantly to perform the same voltage boost, and has inherent limitation to inrush current at startup. The control strategy of the proposed Z-source inverter is exactly the same as the traditional one, so all the existing control strategy can be used directly. A soft-start strategy is also proposed to suppress the inrush surge and the resonance of Z-source capacitors and inductors. The operation principle of the proposed topology and comparison with the traditional topology are analyzed in detail. Simulation and experimental results are given to demonstrate the new features of the improved topology.
