A Modified Virtual Space Vector Modulation Technique for Z-Source NPC Inverters
Journal Title: Carpathian Journal of Electrical Engineering - Year 2018, Vol 12, Issue 1
Abstract
A modified virtual space vector modulation approach for the control of a Z-source neutral point clamped inverter is presented in this paper. This approach works perfectly for the traditional neutral point clamped inverter. In this paper, the effectiveness of the virtual space vector modulation technique in balancing the input capacitor voltages of the Z-source NPC inverter with no low-frequency oscillations superimposed in addition to voltage buck-boost capability is demonstrated through simulations in SABER®. A prototype converter is used to capture experimental results for validation.
