Appropriately selected variable frequency power supplies based on load characteristics
The variety of variable frequency power supplies available on the market is increasing, and their functionalities are becoming more advanced. The performance of variable frequency power supplies is increasingly becoming a decisive factor in the quality of speed regulation. Besides the "innate" manufacturing process conditions of the variable frequency power supplies, the control method used is also very crucial. The table below summarizes the performance characteristics of various control methods for variable frequency power supplies in recent years. In summary, by selecting different control methods for variable frequency control of asynchronous motors, different characteristics of speed regulation can be achieved. Aviation ground power 2, 36V aviation power supply 1, 400Hz variable frequency power supply 7, 115/200V power supply 2, 27V DC power supply 5, 400Hz power supply 12, aviation power supply
Select protective structure for variable frequency power supply based on installation environment
The protective structure of inverter power supplies must be compatible with their installation environment, which requires considering factors such as environmental temperature, humidity, dust, pH level, and corrosive gases. This is crucial for the long-term, safe, and reliable operation of inverter power supplies.
