Single-phase transformerless nine-level inverter with voltage boosting ability for PV fed AC microgrid applications
TL;DR: In this article , a new single-stage common ground type nine-level (9L) switched-capacitor inverter topology with single-phase operation is proposed to reduce leakage current, voltage boosting and maintain the voltage across the switched capacitors.
Journal ArticleDOI
