Laser Power Supply Technology in Pulse Electric Field Test

Study on electric field induction energy extraction of distribution lines based on pulse power technology

“…At present, the commonly used power supply mode of monitoring devices is mainly to convert intermittent energy such as solar energy and wind-solar complementary energy into continuous power supply through energy storage components such as batteries and supercapacitors. In the engineering calculation model of lightning current waveform, the calculation of time and space distribution of return lightning current is based on the lightning current at the bottom of lightning channel [6][7] . The energy extraction by electric field induction of pulsed power needs to go through four processes: inductive energy storage from electric field, pulse shaping, high-frequency oscillation and mutual inductance output, as shown in Figure 1, in which pulse shaping is the process of development and suppression of air gap discharge.…”

Maximum Power Control Method for Two-branch Online Energy Extraction System

“…It is of significance to design stable, reliable, and efficient electric energy to ensure the smooth operation of transmission lines for condition monitoring and online fault maintenance [1] . At present, the common power supply modes include battery-powered, solar-powered, and laser-powered [2][3] . However, each of these power supply modes has its own shortcomings, which limits its large-scale application.…”
