Abstract
Systems and methods for implementing a ternary driver that provides three voltage levels: a high positive voltage, a high negative voltage and a zero voltage. The ternary driver utilizes a dynamic ground to maintain the mid-level zero voltage level at approximately zero volts allowing for voltage regulation during high voltage scenarios. The dynamic ground can be activated when the measured voltage is outside user defined reference voltage levels.
