Boost Topologies for 1500V Multi-String Solar Inverters April 13, 2020 by Matthias Tauer This article investigates the performance and cost of different boost topologies for 1500V multi-string solar inverters. A bidirectional switch implemented within a single package results in a lower parasitic inductance in the three-level system compared to a solutions based on series-connected, single-switch modules. For the 3L-NPC2 1:1 module arrangement, the loop inductance will increase moderately compared to the 2:1 solution. When Huawei first entered the inverter industry, it made both traditional central inverters and string inverters. Implementing the new chipset in the PrimePACK™ 3+ housing, a new high current power module in half-bridge (FF) configuration with a nominal current rating of 1800 A is feasible and results in the new module type FF1800R23IE7 with full current rated IGBTs and full current rated diodes. In contrast to other SiC MOSFETs in the market, no external SiC FWDs are needed. This allows using this solution in reactive power mode for regions with unstable grid conditions. First Solar Module Designed for Efficiency in 1500VDC Applications. The MPP tracker scans the maximum power point regularly to make sure the inverter works at the maximum power of PV strings, minimizing the impact of partial shadows and ultimately producing more electricity when shading occurs.

With more than 48 years' experience in the power electronics sector, and more than 30-year track record in renewable energy, Ingeteam has designed an extensive range of PV solar and storage inverters with rated capacities from 5 kW up to 7,200 kW. It allows operating the inverter in an almost circular P-Q diagram without a derating on the SiC devices. This device needs to handle high currents during the regular operation as well as overload conditions during grid fault events. At the time of a shrinking feed-in-tariff, Japanese energy companies are concentrated on improving their technology to enable more cost-effective solar energy. var s = document.getElementsByTagName('script'); s.parentNode.insertBefore(ga, s); For a worst-case peak voltage investigation, the full system operating voltage from DC(+) to DC(-) with VDC_System=1500 V is applied in an exemplary lab measurement. The first partially 1,500 Vdc systems were installed by Belectric in Germany in 2012 using inverters and electrical equipment developed by GE (with Converteam’s technology) and Padcon. The successful commercial operation of the unit marks the entry of 1,500-volt solar technology in Japan’s solar market. Inverters convert the direct-current electricity produced by the solar panels into alternating current that can be used in homes and businesses. Even though SiC devices are pricey and the required gate-driver concepts are more sophisticated with respect to, e.g., active-miller clamping for suppressing parasitic turn-on, significant improvements are achieved in terms of losses. A loop inductance of such a 1:1 system of approximately Ls=35 nH is feasible. Shadow Scan function activated. A significant advantage of the proposed modulation scheme, in combination with the A-NPC topology, is the ability to work in an almost circular P-Q diagram without a current derating on the SiC devices. The basic schematics for both variants are depicted in Figure 2.
