The low frequency inverter 48v manufacturer said that many people will encounter some problems that they do not understand, such as: which frequency does the high frequency and low frequency of the inverter refer to? First of all, let's understand what is the frequency of the inverter and what does it represent?

The low frequency inverter 48v manufacturer tells you that the frequency of the inverter is an important parameter of alternating current, and it is the number of times the current changes positive and negative per second. Also called cycle. The number of positive and negative half-cycle changes per second.
The national power standard is 50 Hz. In general, the period is 20MS, F 1/T 50HZ.
The frequency of the electricity we use every day is 50Hz, and if we want to change its frequency, we have to change it through a frequency converter. The working principle of the inverter is to first convert the alternating current with frequency into direct current without frequency, and then control it through the electronic circuit so that it can arbitrarily adjust its frequency of alternating current. The manufacturer of low frequency inverter 48v tells you that the inverter is similar to the second half of the inverter, which is to change the direct current into alternating current.
Generally, at a frequency of 30-50HZ, which is too high, the work of the power switch tube may be abnormal, including serious heat generation and too small magnification. The low frequency inverter 48v manufacturer tells you that when the frequency of the inverter is greater than 50HZ, it can become a high frequency inverter.
The operating frequency of the high-frequency transformer inside the inverter is generally around 30K, and it is best not to exceed 40,000 HZ to be stable. At high frequency, the switching tube heats up too much and the tube is hard to find. Switching loss. It is obvious above 100k Hz, and some hundreds of K to several megabytes are resonant.
However, in the case of switching power supply inverters, there is no fixed range for this frequency. It is mainly determined by pwm chips. Some chips can adjust the frequency. There are dozens of k, hundreds of k, and several M. It mainly depends on your own design requirements. It has a great relationship with the parameters of the switch tube and transformer, and the frequency of use is determined by the device and external circuit, not a definite value. The low frequency inverter 48v manufacturer tells you to look at your actual power supply. Different power supply frequencies are different.
