A Single-Stage Common Ground-Type Transformerless Five-Level Inverter Topology

Autor: N. Sandeep, Dhafer Almakhles, Arpan Hota, M. Jagabar Sathik

Publikováno v: IEEE Journal of Emerging and Selected Topics in Power Electronics. 10:837-845

In solar photovoltaic (PV) inverters, a separate boost converter is often used to boost the input voltage, increasing the number of components, cost and weight of the systems and losses. To address this issue, a new common ground type (CGT) transform

A Transformerless 1-, 5-Level Half-Bridge PV Inverter Configuration Based on Switched-Capacitor Technique

Autor: Vivek Agarwal, Arpan Hota, Sachin Jain, Sumon Dhara

Publikováno v: IEEE Transactions on Industry Applications. 57:1619-1628

Leakage current is a serious problem in the transformerless solar PV inverter configurations. The flow of leakage current is mainly due to the high-frequency oscillations in the voltage across PV parasitic capacitance ( vCPV ). Half-bridge (HB) and c

An Improved T-type Switched-Capacitor Based 3-level 3-Phase Inverter with Common Mode Voltage Elimination and Voltage Boosting Capability

Autor: Vivek Agarwal, sachin jain, venu sonti, sumon dhara, Arpan Hota

Zero common mode voltage (ZCMV) space vector modulation (SVM) strategy applied to a three-phase multilevel inverter (MLI) eliminates the common mode voltage (CMV). However, the usage of ZCMV-SVM strategy reduces the number of levels in the output vol
