Power Supply of IGBT High－ voltage Frequency Conversion Governor
Due to the development of power electronics technology, the static frequency converter composed of power semiconductor devices is now very mature, and thus the variable voltage variable frequency (VVVF) speed regulation of AC motors has become more and more popular, and its superiority is also widely known. But frequency conversion speed control is still mainly […]
What are the benefits of using frequency converter for companies building product testing workstations?
Now there are many instrumentation manufacturers, often some manufacturers in the product testing, ignoring the establishment of a product tester workstation. Perhaps some people simply do not take it as a matter of fact, the establishment of product testing workstations used to frequency converter for the enterprise what are the benefits? If the place to test […]
Why is the three-phase frequency converter unbalanced? How to deal with it?
How to deal with three-phase inverter power supply appears unbalanced？
How to make measurements on frequency converter ripple voltage
By measuring the operating voltage and current, it is possible to determine the effectiveness of the application of the relevant electronic components as well as the cause of control circuit problems. Dangerous accidents can easily occur when operating voltages or currents are too high and out of the standard range in the use of frequency converter. […]
