Abstract

The invention belongs to the field of electronic design, and particularly relates to a relay coil IPT system optimization method and system, and the method comprises the steps: building an equivalent circuit model of a to-be-optimized relay coil IPT system; obtaining a corresponding efficiency model according to the equivalent circuit model; analyzing the efficiency model to determine influence factors; and based on the influence factors, obtaining a corresponding optimal load value and an optimal input voltage when the relay coil IPT system is at the highest efficiency. By establishing the equivalent circuit model, the complexity of circuit analysis can be reduced; the efficiency model is established to analyze the influence factors, so that the factors influencing the relay coil IPT system can be further determined, and the corresponding optimal load value and the optimal input voltage can be determined according to the influence when the highest efficiency is determined subsequently.

Description

technical field [0001] The invention belongs to the field of electronic design, and in particular relates to an optimization method and system of a relay coil IPT system. Background technique [0002] Wireless Power Transfer (WPT) is an emerging technology that can transfer energy from the power supply side to the load side without direct contact. The way to apply electrical energy is more flexible. Among them, the inductive power transfer technology (Inductive PowerTransfer, IPT) has been widely used in the field of wireless charging of implantable medical equipment, electric vehicles, mobile phones and other mobile devices due to its advantages of safety and reliability. [0003] The traditional IPT system usually includes two parts: the energy transmitting end structural unit and the energy receiving end structural unit. The structural unit of the energy transmitter includes a high-frequency inverter, a transmitter resonance compensation network and a transmitter coil. ...
