Patent attributes
In an energy treatment apparatus, maximum source electric power of source electric power output from an electric power source is defined, first energy is generated by supplying first driving electric power to a first energy generator due to the source electric power, and second energy is generated by supplying second driving electric power to a second energy generator due to the source electric power. A controller keep the sum of the first driving electric power and the second driving electric power that are supplied per unit time less than or equal to the maximum source electric power of the electric power source continuously with time.
