ECRH is the main heating method for both the W&-As stellarator, which is operational, and W7-X, which is under construction. An overview on physics studies on Electron Cyclotron Resonance Heating and EC Current Drive is an extended parameter range at w7-AS is presented. Experiments were performed with an upgraded ECRH power of up to 1.3 MW at 140 GHz. Electron temperatures of up to 5.7 KeV were measured, which can only be explained by the beneficial effect of positive radial electric fields. ECCD experiments at high power density are discussed, where the assumptions of quasi-linear theory are violated.
