Abstract

The invention provides an ECPT system with a double T-type resonant network and a parameter designing method thereof. Two T-type resonant networks are arranged at an electric energy transmitting end;the first T-type resonant network is a T-type LCL resonant network composed of an inductor L1, an inductor L2 and a capacitor C1; the second T-type resonant network is a T-type CLC resonant network composed of a capacitor C2, an inductor L3, and an equivalent capacitor Cs of an electric field coupling mechanism; an input end of the first T-type resonant network is connected to an output end of aninverter, and an output end of the first T-type resonant network is connected to an input end of the second T-type resonant network; and two ends of the inductor L3 in the second T-type resonant network are correspondingly connected to two emitting pole plates connected of the electric field coupling mechanism respectively. The effect is that the ECPT system can efficiently provide the required power to a load after the load is put in (loaded in) without any additional detection and control circuitry, works in a low-power standby state after the load is cut off (removed), and reduce the systemcost and the controller design difficulty.

Description

technical field [0001] The invention relates to wireless energy transmission technology, in particular to an ECPT system with a double T-shaped resonant network and a parameter design method thereof. Background technique [0002] Wireless Power Transfer (WPT) technology uses soft media such as magnetic fields, electric fields, lasers, and microwaves to realize the non-electrical contact transmission of electric energy from the power supply system to the electrical equipment, completely getting rid of the shackles of conductor connections, so it is convenient and flexible. , safety, reliability and other advantages. As a flexible access and transmission method of electric energy, its broad market prospect and scientific research value are increasingly attracting the attention of experts and scholars all over the world, and it has become a research hotspot in the field of modern electrical engineering and automation. Among them, the power transmission method based on electric...
