1. What is inductive load?
High-power electrical products made by electromagnetic induction, such as motors, compressors, fluorescent lamps, etc., require a current much larger than the operating current when starting. For example, a refrigerator consumes 100W of power during normal operation. about,
But its starting power can reach more than 900W.
Because the inductive load will produce a back electromotive force voltage at the moment when the power is turned on or cut off. The peak value of this voltage is much higher than the voltage value that the inverter can carry. It is very easy to cause instantaneous overload of the inverter and affect the health of the inverter. The service life of the inverter. Therefore, this type of electrical appliances have higher standards for power supply waveforms.
2. What are continuous output power and peak output power?
Some inductive loads, such as refrigerators, washing machines, air conditioners, water pumps, coffee machines, electric drills, etc., require a very large current to propel them at the moment of startup. If the startup is successful, only a smaller current is needed to maintain normal operation, so for As far as the inverter is concerned, there is also the concept of continuous output power and peak output power.
The continuous output power is the rated output power. Generally, the peak output power is twice the rated output power. It is worth mentioning that the current required to start up air conditioners, refrigerators, etc. is usually 3-9 times the normal operating current, so it is necessary to have an inverter that can reach the peak power of the appliance to ensure normal operation.
