Abstract
A current mode hysteresis controller for an inverter circuit provides selectable hysteresis bands based on the level of current to be provided. In the preferred embodiment of the controller, selected upper and lower limits are provided with hysteresis band switching being performed by selecting the amplification factor of error signals used to control the current mode hysteresis controller.
