Low field MRI has gained interest in recent years as a way of providing MRI to under-served and remote settings. MR hardware designed for such applications should be robust, portable and easy to maintain. In this work we present the design of a three-axis gradient amplifier capable of an output current of up to 15 amperes. The gradient amplifier is designed to run off two car batteries and consumes less than 100 watts during imaging. The components in the gradient amplifier are designed to be easily repairable and commonly available.
