By: Contributor(s): Material type: TextTextLanguage: English Publication details: Cairo : Mai Mahmoud Abdelaziz Mohamed , 2021Description: 80 P. : charts , facsimiles ; 30cmOther title:
  • تصميم وتطوير أجهزة حصاد الطاقة للأنظمة الذكية [Added title page title]

  • Issued also as CD
Dissertation note: Thesis (M.Sc.) - Cairo University - Faculty of Engineering - Department of Electrical Power and Machines Summary: The wireless sensor nets (WSNs) have an effective and efficient for Condition monitoring. Batteries are vital sources in many WSNs applications. But it poses a lot of problems. Energy harvesting can be an attractive solution. Piezoelectric energy harvesters (PEHs) used in this thesis which have different advantages.The integrated circuit (ICs), which supply the sensors, have been limited for low output power applications under 1 Watt.So, a proposed converter has attracted this issue of convert microwatt or milliwatt level power from the environment. It presented as a single-stage ac to dc converter, which is based on power factor correction (PFC) topology. Where the harvested energy is 300 æW, it has seen that a total power loss of the proposed system is 102.05 æW. So, the proposed topology proves to be superior over other techniques and suitable for low micro watt power applications
