Abstract :
The authors discuss a power supply configuration based on a switching converter, with reasonably fast dynamic response and low ripple content, so that the linear power supplies can be replaced in four-quadrant DC magnet power supply applications. A new power supply configuration, based on the combination of a frequency converter and a dual converter with circulating current, is proposed for application in four-quadrant DC magnet power supplies. The dual converter is used with circulating current mode for smooth transition of output current polarity. The frequency converter is used at the front of the dual converter to boost the AC line frequency so that the dynamic response can be improved without increasing the ripple content
