Abstract	In the HTS magnet consisting of pancake windings, all pancake windings have been connected in series and excited by a single power source. Most of the pancake windings cannot conduct their critical current values at single power excitation. Current of each winding can be controlled separately to its critical current at multiple power excitation. This paper presents the excitation of an HTS YBCO magnet consisting of pancake windings by multiple power sources. To estimate the critical currents of the pancake windings more precisely, the magnetic field variation in the HTS wire was considered. Properties of multiple power excitation were measured by using the HTS YBCO magnet consisting of 8 pancake windings. Test results showed calculated currents agreed very well with measured ones and central magnetic field increased by multiple power excitation.
