EnglishGujing's innovative inductance design addresses the auxiliary power supply needs of three-phase photovoltaic inverters
Project Background
As a key component in the solar power system, the performance of the photovoltaic inverter directly affects the energy conversion efficiency of the entire system. In this field, the role of auxiliary power supply is crucial. As the core electronic component in the auxiliary power supply, the performance and size of the inductor are crucial to the overall design of the inverter.
Project Dilemma
Gujing has launched a new type of inductor product specifically designed for the auxiliary power supply of three-phase photovoltaic inverters. This inductor not only meets the voltage withstand requirements but also boasts a large inductance and precise inductance control. It can effectively ensure the stability and reliability of the auxiliary power supply.
The introduction of this inductor is driven by the urgent demand from customers for high-performance and miniaturized inductors. In three-phase photovoltaic inverters, the stability of the auxiliary power supply system is crucial. Our customers have put forward a series of specification requirements:
01 Voltage withstand requirement: The inductor must be capable of withstanding the high voltage that may be generated during the operation of the inverter, ensuring stable operation even under extreme conditions;
02 Large inductance and accuracy: It is required that the inductance has a large inductance value, and within this inductance range, the accuracy is required to be controlled within a specific range to ensure the stability of power output and filtering effect.
03 Dimensional specifications: The overall dimensions of the inductor must be controlled within a length of 18mm, a width of 13mm, and a height of 20mm.
Gujing Solution
In response to this customer demand, Gujing's solution is to adopt high-precision automated winding equipment and rigorous quality control processes, ensuring product consistency and reliability. Each batch of products undergoes strict quality inspection, including voltage withstand testing, inductance measurement, and dimensional inspection, to ensure that each inductor meets customer requirements.
Advantages of Gujing
The successful launch of this inductor not only demonstrates GooJing's capability in the field of inductor technology, but also provides a high-performance and miniaturized solution for auxiliary power supply of three-phase photovoltaic inverters, which is conducive to promoting technological innovation and application expansion in the new energy field.
