Problems solved by technology

This requires the generator to have a communication function. At the same time, the power of the system is large, that is, if the current is large, it will generate a lot of reactive heat and reduce the conversion efficiency. This cannot solve the problem for general power amplifier circuits and power amplifier power supplies.
