Abstract: An amplifier has a dual bridge design with two bridge amplifiers. A mode switch enables them to be configured in a series amplification mode. The switching of the mode switch is dynamic and enables re-use of signal current thereby improving overall system efficiency. A delay to the mode switch closure is provided in the event of clipping of one of the amplifier outputs. This prevents large cross currents from flowing.
