Introduction 1
The GRASI Unit (GRradient And Shim Interface) is an interface device designed
to drive several gradient amplifiers. Its main function is to lead the gradient pulse
sequence signals coming from the Gradient Control Unit to the different amplifiers
(X, Y, Z and B0 channels). The integrated power control function protects the
gradient set connected to the amplifiers from over_voltage, over_current and the
duty cycle is controlled to avoid any power excess on the loads.
