Problems solved by technology

2) Large deviation tolerance
Different from the traditional research on maximum efficiency tracking of single-excitation systems, the main challenges faced by multi-excitation systems are: (1) the system characteristics are complex, and it is difficult to find the maximum efficiency solution; (2) multi-variable coupling parameters make parameter OBS difficult
Observation tracking control (3) requires fast response speed, which increases the difficulty of observation and the complexity of control

Abstract

The invention discloses a cooperative control method of a wireless power transmission system based on multi-coupling parameter identification. The method designs a simple tracking control strategy, which can realize dynamic tracking of the system by adjusting the input voltage of the primary side resonant circuit. The maximum efficiency point, the system only needs to control the DC input current of the inverter circuit and the duty cycle of the DC / DC converter to achieve the maximum efficiency of the system, and the observation process of the DC current is simple and easy, so this tracking method is simple It is easy to implement and can also guarantee the response speed.

Description

technical field [0001] The present invention relates to the technical field of radio transmission, and more specifically, relates to a cooperative control method of a wireless power transmission system based on multi-coupling parameter identification.
