Abstract

The invention relates to a modular inverter source system for a wireless power transmission system, comprising a first module and at least one second module, the first module includes a first controller, a first power converter and a first full-bridge inverter converter, and the first controller sends driving signals to the first power converter and the first full-bridge inverter respectively, and the second module includes a second controller, a second power converter and a second Two full-bridge inverters, and the second controller sends driving signals to the second power converter and the second full-bridge inverter respectively, and the first controller collects the total output current and calculates it in real time A current reference, the first controller sends a full-bridge inverter clock signal and a current reference to the second controller. The invention ensures the reliability of system control and saves control resources.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a modular inverter source system of a wireless power transmission system. Background technique [0002] With the outbreak of environmental pollution and oil crisis, the advantages of using electric energy as the power source of mobile devices are becoming more and more prominent. However, there are many problems in the traditional way of using contact power supply or carrying batteries. For example, the contact power supply is limited by the interface, and the power supply track and the receiving head of the mobile device have contact loss, which requires frequent maintenance. Carrying batteries will be restricted by battery size, focus, and cost, which will affect the mileage of mobile devices. At the same time, sufficient basic charging facilities need to be built on the ground, so problems such as inconvenient power supply, poor battery life, maintenance costs a...
