Analysis and Design of Conditioning Circuitry Used for Energy Scavenging Device

Abstract:

Article Preview

Energy scavenging device used for smart grid can achieve energy from electromagnetic field and convert it into electricity to power wireless sensors within substations. Due to the energy collected by the energy scavenging unit is unstable, a conditioning circuitry is essential. A conditioning circuitry is proposed, and modeling method is also established accordingly. Both large-signal model and dynamic disturbance model of the topology are presented as to analyze the static and dynamic characteristics. Remarkably, one duty cycle of the sensors is divided into the launch period and dormant period. At different period, their equivalent impedance is different, so the performance of conditioning circuit at different stages is analyzed. To realize it, a feedback control circuit should be considered in the design of the topology. Further, simulation based on PSIM is done to certify effectiveness of the proposed topology and optimized parameters.
