Tips: Accuracy of solar inverter MPPT sampling circuit
There are a great variety of methods to realize solar inverter MPPT function. However, no matter which method is used, it is firstly required to measure the component power change and then react to the changes. The most critical component in this process is the current sensor. Its measurement accuracy and linearity error will directly determine the hardware efficiency. There are mainly two kinds of current srnsors: Closed-loop and open-loop types. The open-loop current sensor is generally the voltage type, which has the small size, light weight, no plug loss, low cost and the linear accuracy of 99%. Its total measurement error is about 1%. As to the closed-loop current sensor, its frequency band scope is wide, the accuracy is high, the response time is fast, and the interference resistance ability is strong. Its linear accuracy is around 99.9% and the total measurement error is 0.4%.
When the weather condition changes fiercely, the closed-loop sensor has advantages.
