Solar voltage stabilization processing unit

Abstract

The invention provides a solar voltage stabilization processing unit which comprises an input end, a voltage stabilizing circuit, a control unit and an output end. The input end is connected to a photovoltaic power generation unit; the output end is connected to a load; the voltage stabilization circuit comprises a filter circuit and a rectifying circuit and is connected between the input end and the output end and used for performing voltage stabilization processing on inputted voltage signals; the control unit is connected between the input end and the voltage stabilization circuit, and three ways of control signals outputted by the control unit are respectively connected with three active elements in the voltage stabilization circuit. The solar voltage stabilization processing unit has the advantages of simple circuit structure, and voltage stabilization processing can be performed on voltage larger in variation range and generated from the photovoltaic power generation unit, so that stable and uniform output voltage values (or current values) can be obtained, utilization rate of electric energy can be increased to the greatest extent, and convenience is brought to subsequent accessing of the loads.

Description

technical field [0001] The invention relates to electronic circuit technology, in particular to a solar voltage stabilizing processing unit. Background technique [0002] The development and utilization of renewable energy (such as solar energy) has always been a matter of great concern to people. As we all know, the direct current generated by solar photovoltaic power generation is neither uniform nor suitable for transmission, so it needs to be converted before it can be used for industrial or household use. In most cases, the power conversion process needs to be completed by specific steps (such as energy storage, inverter, rectification, filtering, etc.), among which the rectification circuit and filter circuit technology are relatively mature, the circuit structure is clear, and the energy transmission and conversion The efficiency is also the highest, reaching 85% or even higher efficiency. [0003] However, since the energy directly obtained by the photovoltaic powe...
