Amplification systems and methods using fixed and modulated power supply voltages and buck-boost control

The amplifying the vibration amplitude form a first saturation power amplifier of the voltage power supply the signal, in order to generate the vibration amplitude a first output signal. Is a filtering to the vibration amplitude form a second saturation power amplifier for modulating voltage power supply the signal, in order to the vibration amplitude is fixed to the vibration amplitude change the signal, the modulation supply voltage and third/non-inverted control signal and output signal. Combination to the the first load and output signal. While generating to the third/non-inverted control signal modulated to the modulation voltage power supply, to make the first and second output signal of the load combined amplifying to the vibration amplitude change the signal. The vibration amplitude change signal is connected with a phase of the vibration amplitude and speed change of.
