Abstract
The present application discloses a gradient power amplifier debugging method and system. The method may comprise initializing a control unit of the gradient power amplifier debugging system; retrieving a characteristic output of the control unit; computing a load inductance parameter L according to the characteristic output; and adjusting the control parameter of the control unit according to the load inductance parameter L. The control unit may comprise a close-loop control sub-unit, or a feedforward control sub-unit. The characteristic output may be representative of the difference between an output signal and an input signal of the gradient power amplifier debugging system. The control parameter may comprise a proportional coefficient, an integral coefficient, or a cutoff frequency of the filter.
