Abstract

The invention provides an LCL type induction electric power transmission control device. The LCL type induction electric power transmission control device comprises a primary grade part and a secondary grade part, and is characterized in that the primary grade part is provided with two closed loops, namely a frequency converting control loop and a phase-shifting control loop; the frequency converting control loop adopts a frequency tracking method to control the frequency of a high-frequency inverter circuit door control signal; and the phase-shifting control loop adopts a phase-shifting control policy of an intelligent subdivision control algorithm to control a phase-shifting angle of the high-frequency inverter circuit door control signal. The LCL type induction electric power transmission control device is only used for controlling at the primary grade, and a conventional information feedback channel does not need to be used between the primary grade and the secondary grade.

Description

technical field

[0001] The invention relates to the field of inductive power transmission, in particular to an inductive power transmission control device for an LCL type IPT system, and also relates to an LCL type inductive power transmission control method. Background technique

[0002] Inductive power transfer (IPT) is a non-contact power transfer technology based on the principle of electromagnetic induction. It has the advantages of safety and reliability. Application prospects.

[0003] The LCL type IPT system consists of a DC power supply, a high-frequency inverter circuit, a primary resonance circuit, a secondary resonance circuit, an uncontrollable rectifier bridge, a filter link, and a load. By using resonance compensation technology to control the operating frequency of the system to the primary resonance frequency, it can improve System transmission performance, but also can reduce costs. However, the dynamic change of the load during the energy transmission pr...
