摘要：With the rapid development of Chinese power industry, the wireless sensor technology has become an important part of realizing the intelligent construction of the power grid. However, the problem, that how to convert the energy collected by wireless storage device into stable DC output for wireless sensors, has limited the large-scale of wireless sensor. Therefore, it is an urgent need to design conditioning units for wireless energy harvesting device. According to the actual situation of the substation and the lower efficiency of traditional energy harvesting device, this research has proposed a new type of spherical capacitive energy converters topology, and designed energy collected and accelerated circuit and the PWM double-loop controlling and conditioning circuit with rectifier, storage and voltage regulation function. Besides that, the main parameters have been determined by theoretical calculation, and the conditioning circuit is simulated by PSIM simulation software. The simulation results verify the effectiveness of the mentioned topology and parameter selection method.
