[0002] Solar cell, also known as "solar chip" or "photovoltaic cell", is a kind of photoelectric semiconductor sheet that uses sunlight to directly generate electricity. Generate current. In the photovoltaic power generation system, due to the particularity of photovoltaic power generation operation, many electrical equipment in the photovoltaic power generation system need to be tested for low frequency, overfrequency, overvoltage, undervoltage and many other items before leaving the factory and in daily use. , and currently when testing these items, it is necessary for the testing equipment to not only provide specific voltage, current and other electric energy output to meet the various testing contents, but also need to be able to effectively detect solar energy in photovoltaic power generation according to the power generation characteristics of photovoltaic power generation equipment. The various operating conditions of the battery are simulated. The power supply of the currently used photovoltaic inverter testing equipment is often directly rectified and converted into DC for driving or directly driven by the DC power supply. Such power supply equipment Although it can meet the power output required by various testing items, it is indeed impossible to effectively simulate the specific operation of the photovoltaic power generation system. Meet the needs of detection work, not easy to popularize and use
