High-efficiency driver circuit for capacitive loads |
摘要 |
A circuit for driving capacitive loads in a highly efficient manner. In one embodiment, a drive portion is connected to at least one end of a capacitive electric load being applied a voltage waveform. The embodiment further comprises a switching circuit portion having its output connected to the above one end of the capacitive load in order to supply a fraction of the overall current demanded by the load. Additionally, a switching circuit and accompanying switching method provide for efficiently supplying peak current to the capacitive load during voltage fluctuation in the voltage waveform. Briefly, the invention is a circuit arrangement aimed at providing a highly efficient drive for the capacitive load, using a combined linear/switching setup and without distorting the quality of the waveform generated across the capacitive load.
