ABSTRACT:
This invention employs timing circuitry for each voltage source in a multilevel power supply for an amplifier to control the change in voltage outputted from the associated voltage source over time or slew rate when that voltage source is switched on or off preventing large instantaneous voltage increases at the input of the amplifier from occurring when a combination of the voltage sources supplying the amplifier is switched to a different combination upon the output voltage of the amplifier changing.
