1. 1. RF Compressor (SLED) Phase-Modulation to Reduce Peak Fields in the MAX IV Linear Accelerator

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Joel Ekström; [2023]
   Keywords : Accelerator; MAX IV; LINAC; Phase-modulation; SLED; Pulse compression; Technology and Engineering;

   Abstract : Modern particle accelerators need strong electric fields in order to produce high energy particles. Such high voltages are typically reached by injecting pulsed radio frequency power through several steps of amplification. At the end, pulse compression is used to further improve the energy gain at the cost of pulse-length. READ MORE

3. 2. Design of radio frequency energy harvesting system : for use in implantable sensors

   University essay from Linköpings universitet/Elektroniska Kretsar och System; Linköpings universitet/Tekniska fakulteten

   Author : Amir Ebrahimi; David Kihlberg; [2022]
   Keywords : RF energy harvesting; RF rectifier; efficiency; voltage sensor; voltage doubler;

   Abstract : Implantable biomedical wireless sensors provide monitoring of vital health signs such as oxygen, temperature and intraocular pressure and may help to analyse and detect diseases in humans and animals. However, one of the design challenges of implantable devices is providing a safe and reliable energy source. READ MORE

4. 3. Comparison between Active and Passive AC-DC Converters For Low Power Electromagnetic Self-Powering Systems : A theoretical and experimental study of low power AC-DC converters

   University essay from Mittuniversitetet/Institutionen för elektronikkonstruktion

   Author : Ibrahim Hamed; [2020]
   Keywords : Energy-harvesting; electromagnetic; rectifiers; AC DC-converters; Active voltage doublers; Passive voltage doublers.;

   Abstract : Electromagnetic based energy harvesting systems such as Variable reluctance energy harvesting systems (VREH) have shown to be an effective way of extracting the energy of rotating parts. The transducer can provide enough power to run an electronic sensing system, but the problem arises in finding an efficient way of rectifying that power to generate a stable energy supply to run a system, which this report will investigate.

5. 4. A Study on Interface Circuits for Piezoelectric Energy Harvesting

   University essay from Linköpings universitet/Elektroniska Kretsar och System

   Author : Tang Honghao; [2018]
   Keywords : interface circuit; PEH system; switch;

   Abstract : A piezoelectric energy harvesting (PEH) system can harvest electrical energy from ambient vibration energy. In a PEH system, the interface rectifier circuit is critical because it converts AC from the output of piezoelectric harvester to DC that can power the load. READ MORE

6. 5. Power Enhancement in Piezoelectric Energy Harvesting

   University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

   Author : Zohreh Alaei; [2016]
   Keywords : ;

   Abstract : Piezoelectric energy harvesting has been around for almost a decade to generate power from the ambient vibrations. Although the generated power is very small, but there are several ways to increase and enhance the generated power. READ MORE
