The study for developments and economics about the energies from the global warming is very active. For the effective saving and the spanning of the life extension about the 19% rates for the illumination system spending power about the whole electric energies, we proposed the new type of the current control method using a mixing system of the frequency modulation together with the pulse width modulation for the half-bridge power instrument. And we proved the excellence and the stability for our suggested system and analyzed the characteristics.
