Application of Precision Shunt in Solar DC-DC Inverter Conversion Circuit
Writer:Microhm Page View:Date:2018-12-05
The core part of solar photovoltaic power generation is the inverter. The quality of the inverter is important for the conversion rate and power generation rate of the solar power station. In solar photovoltaic power generation, precision resistors and shunts are usually used on the inverter equipment to perform voltage division and splitting. In other new energy generation, such as wind power, precision resistors and shunts are also used in many core components.
The maximum power point acquisition is an important function of the photovoltaic inverter, which not only can effectively improve the irradiation utilization rate, maximize the working efficiency of the photovoltaic inverter, but also change the output voltage and current of the component. The component power is adjusted in time with factors such as sunshine. Especially in low light conditions, the maximum power point acquisition can greatly expand the input voltage of the component, thus achieving the maximum power tracking of the inverter. Precision shunts play a key role in this process and have a profound impact on the use of the inverter and the information in the feedback circuit.
In fact, the inverter function is indeed raising the voltage and realizing the voltage conversion. There are several important elements in this circuit for inductors, switching transistors, diodes, and precision shunts. The combination of these components in the DC-DC circuit allows the inverter to boost, thus changing the voltage switching.

In short, the DC-DC converter, as the core circuit for realizing the maximum power point acquisition function, has been widely used in photovoltaic grid-connected inverters and optical storage and charging fields, and has greatly improved the utilization rate of photovoltaic energy. Especially in practical applications, DC-DC has also developed a characteristic conversion circuit with a precision shunt as its core, which greatly improves the service life of the inverter and the conversion rate of power generation, making solar energy widely used.
