封面故事太阳能逆变器是并网发电关键，合肥阳光冒尖的遮挡都会导致发电量的大阳能光伏电池板的电力输出术，即使是在阵列中其他电都达到最大值，NSC开发了池板出现失配问题时，每块统造成“失配”问题。即使幅下跌。为了使阵列中每一个太 SolarMagic技术。通过该技电池板仍然能输出最大的电光伏系统只受到一点点阴影力。SolarMagic技术运用高级算法和先进的混合信号技术能够监控并优化每块太阳能光伏电池板的产能，因而能够补偿高达50%的因失配问题而产生的发电量损失。SolarMagic电源优化器可快速、轻松地安装在传统太阳能光伏系统中。 “通过使用分布式 MPPT控制则可以减轻遮蔽对系统的不利影响。” Michele Sclocchi表示。最大功率追踪技术(MPPT)透过自动调整太阳能发电系统的输出电路，可补偿太阳能强度、阴影、温度变化、太阳能面板不匹配或老化等可变因素所引起的功率损耗。分布式最大功率追踪 (DMPPT)功能，可以单独补偿每块面板的输出；而集中式MPPT技术则是对在数组内的全部面板施行“最适合”的补偿功能。由于不受相邻模块性能的影响，即便有一个模块失效，每块太阳能面板的输出功率仍可最大化，因此DMPPT是提高太阳能发电系统能源生产率最有前景的技术。 ST整合功率最优化和功率转换功能的太阳能发电系统IC SPV1020，使得 » 上接46页 Junior ad 157mm x 220mm 下接50页 » 48 国际电子商情 | 2010年8月 | www.esmchina.com http://www.icbase.com http://www.esmchina.com
