Abstract
An H-bridge circuit capable of performing switching using one or more intermediate voltage phases each held for a period of time in the midst of the switching operation. This reduces power dissipation associated with the switching operation, while only using one set of high/low voltage supplies. The H-bridge may be used to provide current via an inductor to a load. A class AB amplifier may be placed in parallel with the H-bridge to provide supplemental correcting current to the load to allow the combination to act as an efficient and accurate signal driver. Furthermore, the use of intermediate voltages in the H bridge allows for increased slew rates for any given operation frequency, and allows for the driving of a given signal on the load using a lower operational frequency.
