Abstract
Techniques for efficient operation of a linear stage in an H-bridge system are provided. In an example, a linear stage can switch between voltage regulation and current regulation over a range of a command signal. The particular regulation mode can depend on the regulation mode of a switched stage of the H-bridge system. Efficiency can be realized by using current regulation of the linear stage when the output voltage of the linear stage moves away from the voltage of a supply rail. Such a control scheme can reduce the voltage across the linear stage for a larger range of the command signal resulting in less heat dissipation of the linear stage compared to conventional control of H-bridge linear stages.
