Embodiment 1

[0144] Example 1: For a wireless power transmission system operating at a frequency of 100kHz, the primary side self-inductance of the magnetic coupling structure is 150uH, the secondary side self-inductance is 130uH, the mutual inductance between the primary and secondary sides is 30uH, and the output of the front-stage inverter For 100V, the optimization method using SS new compensation method is as follows:

[0145] When the output needs 100V, that is, the transformation ratio n is 1. Use the parameters of the above formula (1) to design C p 21.1nF, C s 25.3nF, the output side can achieve the effect of constant voltage output of 100V at this time, the simulation results are as Figure 23 Shown

[0146] When the output needs 150V, that is, the transformation ratio n is 1.5. Use the parameters of formula (1) to design C p 19.48nF, C s It is 19.8nF, at this time, the output side can achieve the effect of constant voltage output of 150V. The simulation results are as follows Figure ...

Abstract

The invention relates to a resonance compensation method for a wireless power transmission system with a random constant-voltage output. According to the method, all-range accurate regulation on an output voltage is achieved through a controllable leakage inductance compensation method under the condition of not changing existing SS and PS compensation network structures, and the method has the characteristics of being wide in output voltage range, high in practicability, simple, easy to use and the like.

Description

Technical field [0001] The invention relates to a new method for determining compensation network parameters, in particular to a method for resonant compensation of a wireless power transmission system with arbitrary constant voltage output. Background technique [0002] The wireless power transmission technology is to convert the AC power of the grid into high frequency AC power through rectification, power factor correction and inversion, through the compensation network and magnetic coupling system, the energy is transmitted from the transmitting side to the receiving side, and then through the rectification link and power voltage regulation After the link, the output supplies power to the load. The basic structure diagram of the wireless power transmission system is as follows figure 1 Shown. As an important part of the system, the compensation network has an important influence on improving the power factor of the system, improving the input and output characteristics and i...
