Q: What is the difference between a frequency conversion power supply and a frequency converter? I believe everyone has many questions. I only know that the frequency conversion power supply is not the same product as the frequency converter, but I don't know much about it, some friends may know that the inverter is used for speed control, while the inverter is used to simulate power usage in factories. This explanation is correct, but you know the internal reason why it cannot be used in the same place. The following are some differences between the Chinese port and the Chinese port.
(1) different load types: Variable Frequency Power Supply: Suitable for various types of resistive and inductive loads; inverter: precise control of the load speed of motor, cannot be used for other load tests
(2) Different output frequencies: Variable Frequency Power Supply: under full load conditions, the output frequency stability is 0.01% of the set frequency; inverter: the output frequency changes with the change of the motor's Operating Characteristics
(3) Different output modes: Variable Frequency Power Supply: Single-phase and three-phase output can withstand 100% unbalanced load.
Inverter: only three-phase output, and poor Load Balancing Capability when three-phase
(4) Different filtering devices: Frequency Conversion Power Supply: the output is equipped with a special filtering device, and the output is a high-order harmonic less inverter: the output is not a filtering device, and the harmonic content is high.
(5) different purposes: Variable Frequency Power Supply: by changing the voltage and frequency of the output power supply, and providing pure and stable power supply for the load. Inverter: by changing the frequency and voltage, the motor's slow start function can be achieved. The voltage and frequency change proportionally and cannot be adjusted separately.
The differences include the control mode, isolation pressure change, EMI interference, output waveform and output waveform distortion, and so on. Here we will not explain them one by one. If you want to know more, you can pay attention to the Center Port Yangsheng.
