Abstract

The invention relates to the technical field of electronic circuits, and proposes a photovoltaic power generation system for teaching, which includes photovoltaic modules, a DC / DC circuit and a DC / AC circuit connected in sequence. Both the DC / AC circuit are connected to the main control circuit, and also includes a zero-crossing detection circuit. The zero-crossing detection circuit includes a comparison circuit and a filter circuit that are connected in sequence. The input end of the comparison circuit is used to connect with the voltage sensor, and the filter circuit includes a transistor Q1. , transistor Q2 and NAND gate chip U2. Through the above technical solution, the problem of poor output waveform of the photovoltaic power generation system for teaching in the prior art and affecting students experience is solved.

Description

technical field [0001] The invention relates to the technical field of electronic circuits, in particular to a photovoltaic power generation system for teaching. Background technique [0002] Today's society is facing extremely serious problems of environmental pollution and energy shortage. Due to its own characteristics of high reliability and high cleanliness, solar photovoltaic power generation has become the object of research in various countries due to its inexhaustible advantages. . The photovoltaic grid-connected power generation system for teaching aims to provide students with a teaching experiment platform, so that they can understand the energy provided by solar energy as a new type of energy and master the working principle of the system. Based on the observation and study of the entire platform, understand and be familiar with the development basis and installation precautions of the photovoltaic power generation system. At present, the output waveform of th...
