Since 1996 the DELPHI experiment at LEP collected data at various center-of-mass energies significantly above threshold for W boson pair production. With the collected W pair events, corresponding to an integrated luminosity of ~ 450 pb^-1, the existence of the WWW (V,Z) vertex could be probed and a more precise direct measurement of the Triple Gauge Boson Couplings was obtained.

It is the goal of this poster to give an introduction to the measurement of the charged couplings and to discuss the different approaches and the ongoing analysis. The most recent results on the Triple Gauge Boson Coupling parameters obtained by DELPHI are shown.
