A Hybrid Method for Three-Level T-Type Inverters to Eliminate Neutral Point Voltage Ripple and Control DC-Link Capacitors’ Voltage for Separate MPPT

A Hybrid Method for Three-Level T-Type Inverters to Eliminate Neutral Point Voltage Ripple and Control DC-Link Capacitors’ Voltage for Separate MPPT

Nowadays, photovoltaic (PV) systems based on centralized topology with a three-level T-type (3LT<sup>2</sup>) inverter are used to decrease investment costs and increase conversion efficiency. In this topology, the split capacitors of the DC-link can individually connected to PV arrays....
