Compared with low-frequency signals, high-frequency signals change very quickly and have sudden changes; low-frequency signals change slowly and have smooth waveforms.

2. Power supply and signal are different. The voltage provided by the power board generally has a frequency of 0 (DC power supply) or 50Hz (AC power supply). The signal can be said to be high frequency or low frequency (or other frequencies). It is difficult to say whether the power board is used for power supply, because it is only used for power supply and the frequency is very low. If it must be said, it is only low frequency.

3. The main advantages of high-frequency inverters are light weight, iwọn kekere, low standby power, and relatively high efficiency (jo fifipamọ diẹ ninu awọn agbara).
