专业的设备处理高电压能量收集
能量收集往往涉及权力清除涓涓细流从非常低的能量环境来源。对于这些应用程序,设计人员专注于电路能够转换到最小的可用电压电平的有用功率。与此相反,高能量的来源需要一类电路能够有效地处理高电压水平的能量传感器,如太阳能电池板,热电发电机,压电设备。设计师可以使用从制造商包括线性技术中,半导体、罗姆半导体、意法半导体器件实现高效的高压能量收集系统,德克萨斯文书,其中。
低能量的应用,高效的能量收集芯片等先进设备eh4205线性模块,线性技术LTC3108、德克萨斯文书bq25570旨在清除功率从换能器产生有限的电压水平低20 mV,最大值为6 V左右。在这些系统的核心,升压转换器带来低电压到有用的水平供电电路和充电超级电容器和电池。
High-energy sources and their respecTIve transducers can produce output-voltage levels easily exceeding the maximum input range of these low-voltage devices. For example, solar panels such as the Phoenix Contact 2885456 module produce nearly 18 V output. Driven by high-amplitude vibraTIons in industrial applicaTIons and other high-energy environments, piezoelectric devices can achieve output levels in the tens of volts. Similarly, thermoelectric generators can produce similar voltage output levels when a sufficiently large temperature differenTIal exists between the two sides of a TEG, although achieving that temperature differential can be a difficult task at best.
