This paper presents a DC-AC multi-level converter topology that is well adapted for high voltage conversion ratio and will be used to transfer power between a 1500V DC source and 400V/480V AC load or grid. This topology is intented for 1500V Applications. The main potential applications are Uninterruptible Power Supply (UPS), Solar Photovoltaic (PV) Systems and Energy Storage Systems (ESS). The proposed converter topology achieves very high efficiency, up to 98,7% in single conversion architecture using only low-cost silicon (Si) devices with a low blocking voltage.
