硅与碳化硅混合解决方案在减少尺寸的同时，将输出功率提高了15%

中国上海 - 2024 年 8月 28 日 - 安森美（纳斯达克股票代号：ON ）推出采用 F5BP 封装的最新一代硅和碳化硅混合功率集成模块 (PIM)，非常适合用于提高大型太阳能组串式逆变器或储能系统 (ESS)的功率。与前几代产品相比，这些模块在相同尺寸下提供了更高的功率密度和效率，将太阳能逆变器的总系统功率从 300 kW提高到 350 kW。这意味着，使用最新一代模块的装机容量为一千兆瓦的大型太阳能发电场，每小时可实现近两兆瓦的节能效果，相当于每年为超过 700 户家庭供电。此外，要达到与上一代产品相同的功率，所需的模块数量更少，可将功率器件的元器件成本降低 25% 以上。

由于太阳能发电的平准化能源成本（LCOE）最低，太阳能正日益成为全球可再生能源发电的首选。为了弥补太阳能发电的不稳定性，公用事业运营商也在增设大型电池储能系统（BESS），以确保电网的稳定供能。为了支持这种系统组合，制造商和公用事业公司需要能够提供最高效率和可靠电力转换的解决方案。每提高 0.1% 的效率，对于每千兆瓦装机容量，每年可节省 25 万美元的运营成本。

“作为一种依赖阳光的波动性能源，我们需要不断提高系统效率和可靠性，并采用先进储能解决方案，以确保全球电网在电力需求高峰期和非高峰期的稳定性和可靠性。”安森美电源方案事业群工业电源部副总裁 Sravan Vanaparthy 表示，“更高效的基础设施会促进采用，并确保随着更多太阳能发电设施的建成，减少能源浪费，推动我们在摆脱化石燃料的道路上不断前进。”

F5BP-PIM集成了1050V FS7 IGBT和1200V D3 EliteSiC二极管，实现高电压和大电流转换的同时降低功耗并提高可靠性。FS7 IGBT 关断损耗低，可将开关损耗降低达 8%，而EliteSiC二极管则提供了卓越的开关性能，与前几代产品相比，导通压降（VF）降低了15%。

这些PIM包含了一种创新的I型中点箝位（INPC）拓扑结构的逆变器模块和飞跨电容拓扑结构的升压模块。这些模块还使用了优化的电气布局和先进的直接铜键合（DBC）基板，以降低杂散电感和热阻。此外，铜基板进一步将结到散热片的热阻降低了9.3%，确保模块在重载下保持冷却。这种热管理对于保持模块的效率和使用寿命至关重要，使其在需要可靠和持续供电的苛刻应用中非常有效。
