Abstract

The present invention provides a maximum power tracking power generation device and system. The device includes a power generation component and at least one optimizer, and the optimizer includes a maximum power tracking circuit, a drive control circuit, a first switch and The second switch; the maximum power tracking circuit includes a voltage and current detection unit, a multiplier and a maximum power tracking processing unit; the multiplier is used to combine the component output voltage of the power generation component with the component output current of the power generation component multiplied to obtain the component output power of the power generation component; the maximum power tracking processing unit is used to track and determine the current maximum power of the power generation component according to the component output power, and determine the current maximum power according to the current maximum power. a duty ratio signal, and send the duty ratio signal to the drive control circuit. The invention simplifies the device, effectively reduces the cost, improves the power generation efficiency of the power generation component, and can realize a high degree of integration.

Description

technical field [0001] The invention relates to the field of power generation, in particular to a maximum power tracking power generation device and system. Background technique [0002] Each power generation component has its own output power characteristics, and the maximum power output of the component can only be exerted when it works at a specific voltage and current. However, the output of a single power generation component is often not enough to provide the actual power demand. Therefore, an array of power generation components is usually formed in series and parallel to meet the design requirements. In the existing technology, it needs to be converted from DC to AC after power generation (because the power generation components are all DC, they need to be converted into AC before they are connected to the actual civil or industrial grid. This process is called inverter, that is, DC to AC ) conversion. [0003] In the prior art, the same Maximum Power Point Trackin...
