Abstract: A method for supplying electrical power to a gradient amplifier that drives a gradient coil for a magnetic resonance imaging system is provided. The method includes predicting a gradient voltage required to drive the gradient coil for a scan based at least in part on a gradient coil model. The method further includes calculating a voltage set point for a power supply based at least in part on the predicted gradient voltage. The method further includes providing electrical power to the gradient amplifier via the power supply based at least in part on the calculated voltage set point. The gradient coil model is based at least in part on historical data acquired prior to the scan.
