关于
微型逆变器在户外恶劣环境下运行,因此紧凑型设计、高效率和长寿命是这些设备成功的关键因素。例如,微型逆变器若出现故障,则需要在屋顶上更换零件,价格不菲且耗时耗力。因此,市场要求微型逆变器的使用寿命与光伏组件的寿命相匹配,而光伏组件的典型使用寿命为25年。英飞凌通过卓越的制造工艺、精准的生产检测以及自动化技术,确保了高品质和高可靠性标准。
英飞凌提供种类繁多的产品,涵盖不同封装形式和技术,包括CoolGaN™ HEMTs、OptiMOS™和CoolSiC™ MOSFETs、EiceDRIVER™ 2EDL栅极驱动器IC,以及XMC™或PSOC™高性能微控制器(MCU),助力制造商设计适用于单面板和多面板优化器的高效解决方案。此外,该产品组合还包含 XENSIV™ 高精度霍尔效应电流传感器,以及需要额外存储器时的 EXCELON™ F-RAM。为了将数据从微型逆变器传输到云端,我们 AIROC™ 系列中的各种 Wi-Fi 和 Bluetooth® 产品都能满足应用需求。
英飞凌的 OptiMOS™ 和 CoolMOS™ N 沟道 MOSFET 产品面向广泛的应用,可满足最严格的要求。我们的碳化硅 CoolSiC™ MOSFET 技术开创了灵活性的新时代,使设计人员能够利用前所未有的效率和可靠性水平。此外,我们的高压 CoolSiC™ MOSFET 技术在反向恢复特性方面也有令人印象深刻的改进。
另一方面,英飞凌 CoolGaN™ 是一种高效氮化镓晶体管技术,适用于电压范围高达 600 V 的功率转换。凭借在半导体市场的丰富经验,英飞凌的氮化镓技术使电子模式概念走向成熟,实现了端到端的大批量生产。
每个开关都需要一个驱动器,而正确的驱动器则会产生不同的效果。英飞凌提供全面的 EiceDRIVER™ 栅极驱动器 IC 产品组合,具有各种配置、电压等级、隔离级别、保护功能和封装选项。EiceDRIVER™ 栅极驱动器 IC 与英飞凌 IGBT 分立器件和模块、硅 MOSFET(CoolMOS™、OptiMOS™ 和 StrongIRFET™)、碳化硅 MOSFET(CoolSiC™)、氮化镓 HEMT(CoolGaN™)互补,或作为我们集成电源模块(CIPOS™ IPM 和 iMOTION™ smart IPM)的一部分。
更具体地说,EiceDRIVER™ 2EDL81 系列双通道结隔离栅极驱动器 IC 专为半桥应用中的中等电压功率 MOSFET 而设计。由于微逆变器应用中的 MCU 通常位于低压侧,因此次级(高压)侧需要具有加强隔离功能的栅极驱动器,在此我们推荐使用我们的 EiceDRIVER™ 2EDi 系列栅极驱动器。
与基于磁芯的电流传感器相比,英飞凌 XENSIV™ 系列高精度无磁芯开环电流传感器体积更小,成本也更低。基于英飞凌精确稳定的霍尔效应电流传感器技术,电流传感器的模拟输出信号在温度和寿命范围内都具有高度线性。由于没有铁芯或导磁体,传感器信号没有磁滞和饱和现象。差分电流传感器测量使用了两个霍尔敏感元,即使在嘈杂的环境例如有来自相邻电流线或杂散磁场的串扰(这两者在微型逆变器应用中都很常见),也可确保其高精度。系统设计人员能够对传感器的灵敏度以及两个专用过流信号的阈值电平进行编程,因此无需任何外部组件即可使其适应个性化要求。非接触式电流传感器 IC 还会在电源电压过压或欠压情况下发出警告信号。
微控制器单元(MCU)在单个集成电路(IC)芯片上集成了 CPU、存储器以及输入和输出外围设备。MCU 就像一台小型独立计算机。这可以降低功耗,使设计更紧凑,并节省成本。此外,微控制器还能为嵌入式系统提供功能安全和安保。
同样重要的是,微控制器必须配备先进的安全功能,以避免安全漏洞和防止恶意软件攻击。因此,新一代 32 位 MCU 为一系列嵌入式系统应用提供了强大的保护。英飞凌微控制器产品组合提供全面的产品系列,包括性能卓越、未来经过验证的先进 32 位微控制器,以及传统的 8 位和 16 位微控制器。我们的 32 位 MCU 产品组合包括基于 Arm®Cortex-M® 技术的 XMC™ TRAVEO™ T2G、PSOC™、Auto PSOC™、FM™ 和 MOTIX™ 嵌入式电源(片上系统)。此外,英飞凌还提供采用 TriCore™ 技术的 AURIX™ 系列。
EXCELON™ 系列存储器产品具有高能效、高密度和可靠的数据记录功能。英飞凌的下一代铁电 RAM (F-RAM) 存储器通过将超低功耗操作与高速接口、即时非易失性和无限读/写周期耐久性相结合,提供业界功耗最低、任务关键型非易失性存储器。
了解英飞凌的 AIROC™ Wi-Fi + Bluetooth® 组合产品系列,该产品系列提供广泛的安全、强大的解决方案,使您能够更快地将优秀产品推向市场。AIROC™ + Wi-Fi SoC 包括片上 MCU、存储器和网络协议,您可以轻松创建自己的云连接应用。

每个开关都需要一个驱动器,而正确的驱动器则会产生不同的效果。英飞凌提供全面的 EiceDRIVER™ 栅极驱动器 IC 产品组合,具有各种配置、电压等级、隔离级别、保护功能和封装选项。EiceDRIVER™ 栅极驱动器 IC 与英飞凌 IGBT 分立器件和模块、硅 MOSFET(CoolMOS™、OptiMOS™ 和 StrongIRFET™)、碳化硅 MOSFET(CoolSiC™)、氮化镓 HEMT(CoolGaN™)互补,或作为我们集成电源模块(CIPOS™ IPM 和 iMOTION™ smart IPM)的一部分。
更具体地说,EiceDRIVER™ 2EDL81 系列双通道结隔离栅极驱动器 IC 专为半桥应用中的中等电压功率 MOSFET 而设计。由于微逆变器应用中的 MCU 通常位于低压侧,因此次级(高压)侧需要具有加强隔离功能的栅极驱动器,在此我们推荐使用我们的 EiceDRIVER™ 2EDi 系列栅极驱动器。
与基于磁芯的电流传感器相比,英飞凌 XENSIV™ 系列高精度无磁芯开环电流传感器体积更小,成本也更低。基于英飞凌精确稳定的霍尔效应电流传感器技术,电流传感器的模拟输出信号在温度和寿命范围内都具有高度线性。由于没有铁芯或导磁体,传感器信号没有磁滞和饱和现象。差分电流传感器测量使用了两个霍尔敏感元,即使在嘈杂的环境例如有来自相邻电流线或杂散磁场的串扰(这两者在微型逆变器应用中都很常见),也可确保其高精度。系统设计人员能够对传感器的灵敏度以及两个专用过流信号的阈值电平进行编程,因此无需任何外部组件即可使其适应个性化要求。非接触式电流传感器 IC 还会在电源电压过压或欠压情况下发出警告信号。
微控制器单元(MCU)在单个集成电路(IC)芯片上集成了 CPU、存储器以及输入和输出外围设备。MCU 就像一台小型独立计算机。这可以降低功耗,使设计更紧凑,并节省成本。此外,微控制器还能为嵌入式系统提供功能安全和安保。
同样重要的是,微控制器必须配备先进的安全功能,以避免安全漏洞和防止恶意软件攻击。因此,新一代 32 位 MCU 为一系列嵌入式系统应用提供了强大的保护。英飞凌微控制器产品组合提供全面的产品系列,包括性能卓越、未来经过验证的先进 32 位微控制器,以及传统的 8 位和 16 位微控制器。我们的 32 位 MCU 产品组合包括基于 Arm®Cortex-M® 技术的 XMC™ TRAVEO™ T2G、PSOC™、Auto PSOC™、FM™ 和 MOTIX™ 嵌入式电源(片上系统)。此外,英飞凌还提供采用 TriCore™ 技术的 AURIX™ 系列。
EXCELON™ 系列存储器产品具有高能效、高密度和可靠的数据记录功能。英飞凌的下一代铁电 RAM (F-RAM) 存储器通过将超低功耗操作与高速接口、即时非易失性和无限读/写周期耐久性相结合,提供业界功耗最低、任务关键型非易失性存储器。
