1. What is VF controlFor asynchronous motors, in order to ensure that the motor flux and output force remain unchanged (constant torque). When the motor changes frequency, the ratio of voltage V and frequency F needs to be maintained approximately unchanged. This method is what we called constant vo

What are the requirements for the working environment of the inverter?The frequency converter can work safely and reliably only in the specified environment, and if the environmental conditions do not meet its requirements, the corresponding improvement measures should be taken.The operating environ

In what ways does the inverter protect the motor?1 Overvoltage protectionThe output of the inverter has a voltage detection function, and the inverter can automatically adjust the output voltage so that the motor does not suffer from overvoltage. Even when the output voltage adjustment fails and the

PV inverter is the core component in PV power generation system, and MPPT technology is the core technology of PV inverter, then, what is PV MPPT?Maximum Power Point Tracking (MPPT) system is a kind of electrical system. It can make the photovoltaic panels output more electricity by adjusting the wo

At present, energy has become a major issue of common concern to the international community. Photovoltaic power generation is receiving more and more attention because of its renewable and clean characteristics. Developed regions and countries such as Europe, the United States and Japan have invest
