چکیده
This article presents a single-shunt measurement of three-level inverter using modified space-vector modulation to reconstruct the three-phase load current. The proposed method was implemented on digital signal processor (DSP), and algorithm verified in laboratory experiment. Through work, it proven that current could be performed for inverters an analogous way ordinary inverters. Three-phase reconstruction with eight vectors, but inverters, 21 vectors were available. When working edges between two disturbances appeared as spikes. problem solved SVM by shifting signals. Carefully designed (vector injection) demonstrated excellent currents measured.

Space Vector Pulse Width Modulation with Reduced Common Mode Voltage and Current Losses for Six-Phase Induction Motor Drive with Three-Level Inverter
Common-mode voltage (CMV) generated by the inverter causes motor bearing failures in multiphase drives.On the other hand, presence of undesired z-component currents in six-phase induction machine (SPIM) leads to extra current losses and have to be considered in pulse width modulation (PWM) techniques. In this paper, it is shown that the presence of z-component currents and CMV in six phase driv...

Photovoltaic systems integrated to the grid have received considerable attention around the world. They can be connected to the electrical grid via galvanic isolation (transformer) or without it (transformerless). Despite making galvanic isolation, low frequency transformer increases size, cost and losses. On the other hand, transformerless PV systems increase the leakage current (common-mode c...
