Abstract
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.
