High-voltage wideband switching amplifier for capacitive loads

Why is it that arbitrarily driving imaginary loads has always required lots of power? In this thesis, a highly efficient switching amplifier class is developed that is capable of delivering energy to, as well as taking energy from, a capacitive load in a finely controllable, dissipationless manner. Several control schemes were investigated, and a simple version of the amplifier was then built and tested using both synchronous and asynchronous controllers. The amplifier proved to be capable of driving high voltage, high frequency signals across a capacitive transducer with extremely low total power consumption and very low distortion.
