The invention provides a grid-connected inverter controller with solar energy and wind energy integrated. A solar energy and wind energy input end and a solar energy and wind energy output end are arranged on a shell. Direct currents generated by the solar energy and the wind energy pass through a phase tracker, an integrated circuit controller and a power frequency inverter transformer in sequence after passing through the solar energy and wind energy input end, and then alternating currents are output by the output end. A current and voltage output feedback comprises a coil, a precision voltage mutual inductor and a precision current mutual inductor. The precision voltage mutual inductor and the precision current mutual inductor enable collected voltage circuit signals of the coil to be connected with the phase tracker, the integrated circuit controller and the power frequency inverter transformer through cable feedback. The grid-connected inverter controller with the solar energy and the wind energy integrated has the advantages and the positive effects of being high in system efficiency, high in stability, multifunctional, good in performance, large in power, small in distortion degree, good in anti-interference capability, small in size, small in occupation area, easy, convenient and flexible to operate, and capable of saving energy, protecting environment and greatly reducing operation cost.
Description
technical field [0001] The invention belongs to the technical field of solar and wind energy control system devices, and in particular relates to a solar and wind energy integrated grid-connected inverter controller. Background technique [0002] Solar energy and wind energy are huge amounts of renewable energy, and solar and wind energy have great limitations in forming a power supply system with direct current. Fluorescent lamps, refrigerators, and electric fan lamps cannot be powered by DC power. Therefore, the power supply system requires an inverter device. [0003] In the existing technology, the inverter equipment has technical problems such as expensive price, poor performance, unsafe grid connection and lagging inverter technology. Contents of the invention [0004] The problem to be solved by the present invention is to provide a solar wind energy integrated grid-connected inverter controller with simple operation, high production efficiency, low cost, small si...
