摘要： A method for controlling a fast tracking power supply, a fast tracking power supply, and a system are provided. The fast tracking power supply adopts a combined controllable voltage source to control a load voltage, and the combined controllable voltage source is connected to a tracking current source in parallel to provide a current for a load. The tracking current source is responsible for providing a low-frequency high current for the load to implement high-efficiency low-frequency tracking of the load current and reducing an output current of the combined controllable voltage source as much as possible. Meanwhile, a power supply voltage switching unit in the combined controllable voltage source adjusts a power supply voltage range of a linear amplifier in the combined controllable voltage source, so as to reduce the power supply voltage range of the linear amplifier, thereby reducing power consumption of the combined controllable voltage source. Moreover, because the power supply voltage range of the linear amplifier is decreased, the linear amplifier further implements a higher tracking bandwidth, which improves the whole power amplification efficiency of the fast tracking power supply.

摘要： An amplifier apparatus includes a comparator (20) which compares an incoming signal (19) with a number of reference potentials. A switching stage (22) is controlled by the output of the comparator (20) and is arranged to select a voltage level to be applied to one side of a load (24), such as a loudspeaker system. An amplifier/subtractor (21) is included to subtract from the incoming signal (19) a percentage of the selected voltage level applied to the load. The amplifier/subtractor (21) amplifies the incoming signal (19) minus the percentage of the selected voltage level and applies it to a second side of the load (24). Also disclosed is a method for amplifying a signal.
