Description

technical field [0001] The invention relates to a device and method for converting an audio signal into a controllable power signal. Background technique [0002] In the field of industrial instruments (such as intelligent power distribution instruments), a controllable signal source is often required, such as a 50Hz AC signal with controllable amplitude or a controllable harmonic signal. The main difference between these signals is the frequency components included. The current devices that generate controllable signal sources are mainly based on embedded development to generate signals of specified frequencies, and this method has its limitations. First, the cycle of embedded development is long and the equipment is expensive. Secondly, the signals they generate are often low-power, so if you want to generate a high-power signal, you need to cooperate with other amplification devices, which increases the overall cost and complexity. In addition, this type of equipment i...

AI Technical Summary

Problems solved by technology

First, the embedded development cycle is long and the equipment is expensive

Secondly, the signals they generate are often low-power, so if you want to generate a high-power signal, you need to cooperate with other amplification equipment, which increases the overall cost and complexity

In addition, such devices are generally relatively simple in function. For example, the frequency of AC signals can only be 50Hz, and the harmonics cannot be confused with standard signals, and the range of harmonics generated is also limited.
