Abstract
A switched capacitive device includes a stationary portion including first circuit boards. The device also includes a translatable portion including second circuit boards proximate to, and interdigitated with, the first circuit boards. The second circuit boards are translatable with respect to the first circuit boards. The first circuit boards induce substantially linear motion of the second circuit boards through the use of an electric field induced by the first circuit boards. The device further includes a control system including switching devices and a controller coupled to the switching devices. The switching devices are coupled to at least a portion of at least one first circuit board. The switching device is configured to intermittently energize and de-energize the first circuit board for predetermined periods of time. The controller alternatingly opens and closes the switching devices through transmitted gating commands as a function of a determined load on the switched capacitive device.
