Patent number: 9425700Abstract: A resonant power supply is disclosed. The resonant power supply includes a series resonant configured to convert an input DC voltage to an output DC voltage. The resonant power supply further comprises a converter controller coupled to the series resonant converter and configured to receive a DC voltage feedback signal measured at the output of the series resonant converter, or a resonant current feedback signal representing a resonant current flowing through the series resonant converter. The converter controller is further configured to generate control signals to be applied to the series resonant converter to limit the output DC voltage of the series resonant converter according to the DC voltage feedback signal and a predetermined voltage threshold signal, or to limit the resonant current of the series resonant converter according to the resonant current feedback signal and a predetermined current threshold signal.Type: GrantFiled: October 24, 2012Date of Patent: August 23, 2016Assignee: GENERAL ELECTRIC COMPANYInventors: Xi Lu, Tao Ma, Yimeng Shi, Pengcheng Zhu, Garron Koch Morris, Juan Antonio Sabate, Jeffrey Neal Slotnick, Wesley Michael Skeffington, Margaret Ann Wiza

Patent number: 9322890Abstract: A gradient amplifier for driving a gradient coil is disclosed. The gradient amplifier includes a direct current (DC) bus for receiving DC voltage generated from a series resonant converter, an inverter coupled to the DC bus configured to receive the DC voltage at the DC bus and convert the DC voltage to generate an output voltage to be applied to the gradient coil, and an inverter controller coupled to the inverter. The inverter controller is configured to generate control signals to control operation of the inverter based at least on a DC voltage feedback signal measured at the DC bus, an output voltage feedback signal measured at the output of the inverter, and a reference output voltage signal indicative of a desired voltage to be achieved at the output of the inverter.Type: GrantFiled: October 24, 2012Date of Patent: April 26, 2016Assignee: GENERAL ELECTRIC COMPANYInventors: Fei Xu, Tao Ma, Xi Lu, Xinhui Wu, Yimeng Shi, Pengcheng Zhu, Garron Koch Morris, Juan Antonio Sabate, Jeffrey Neal Slotnick

Patent number: 9287795Abstract: A resonant power supply is provided. The resonant power supply comprises a series resonant converter configured to convert an input DC voltage to an output DC voltage to generate an output DC voltage. The series resonant converter includes a switching stage, a resonant inductor, a resonant capacitor, and an isolation transformer. The resonant power supply further comprises a converter controller configured to obtain an actual trajectory radius signal based on a resonant inductor current, a resonant capacitor voltage, and a voltage in association with the isolation transformer. The converter controller is further configured to generate a trajectory radius command signal based on a DC voltage command signal and a DC voltage feedback signal, and to generate control signals to be applied to the switching stage based on the actual trajectory radius signal and the trajectory radius command signal.Type: GrantFiled: October 24, 2012Date of Patent: March 15, 2016Assignee: GENERAL ELECTRIC COMPANYInventors: Tao Ma, Xi Lu, Yimeng Shi, Pengcheng Zhu, Garron Koch Morris, Juan Antonio Sabate, Jeffrey Neal Slotnick, Wesley Michael Skeffington, Margaret Ann Wiza
