The two major differences between high frequency inverters and low frequency inverters




In the classification of inverters, there are two most common classifications, one is a high-frequency inverter, and the other is a low-frequency inverter. Here are some points about the high-frequency inverter and the low-frequency inverter. Let's take a look at the difference, and what are the advantages and disadvantages of the two.

The difference between high frequency inverter and low frequency inverter

1. The frequency is different

According to the frequency spectrum division table formulated by the Institute of Electrical and Electronics Engineers (IEEE), the low frequency frequency is 30~300kHz, the intermediate frequency frequency is 300~3000kHz, the high frequency frequency is 3~30MHz, and the frequency range of 30~300MHz is very high frequency. 300~1000MHz is UHF.
Compared with the low-frequency signal, the high-frequency signal changes very quickly and has sudden changes; the low-frequency signal changes slowly and the waveform is smooth.

2. The power supply is different from the signal

The voltage provided by the power board generally has a frequency of 0 (DC power) or 50Hz (AC power). The signal can be said to be high frequency or low frequency (or other frequencies), but the power board is not easy to say. It is only used for power supply, and the frequency is very low. If you really want to say it, it is only low frequency.
