Systems, methods, and devices that employ self-driven gate-drive circuitry to facilitate controlling power switches to emulate a diode bridge to synchronously rectify a power signal are presented. The delivery systems include an inner shaft, an expandable member slidably disposed about the inner shaft and configured to receive the tubular implant, and a tubular outer shaft disposed about the inner shaft. The copy includes a stub-state object. The sum of inductive impedance by internal inductance of the third winding and capacitive impedance by the capacitor is capacitive impedance within a range of rotational speed of the generator. The at least one supporter assembly includes more than one inclined side surface and at least one cavity within one of the inclined surfaces, wherein each cavity receives an end of the at least one fluorescent lamp.
