How To See The Quality Of The Inverter? The Easiest Way To Judge Whether A Frequency Converter Is Good Or Bad

The quality of the inverter is not good. The easiest way to judge whether a inverter is good or bad is to check the power. When testing, it is better to connect a motor with a power less than the rated power of the inverter at the output of the inverter. The internal software is good or bad, especially the low-frequency and high-torque after power-on is a direct and effective method to test the inverter algorithm. After changing the parameters, the inverter is modulated within 5HZ to see if the load motor torque is weakened or not. Whether it changes evenly, then it is to observe whether the output waveform of the inverter is perfect, and it is to start and stop frequently in a short time to see the peak value of current and voltage. These methods can verify the performance of the inverter software.
