摘要： A light source assembly includes multiple light emitters having output that are focused and mixed onto a optical fiber leading to an endoscope or other device. The emitters can be LEDs or solid state lasers that emit different colors. A driver circuit controls the relative output intensities of the light emitters so as to produce a desired light spectrum. A driver circuit includes a buck topology connected to a controller that provides current mode control. Pulse width modulation of the buck current is provided by a semiconductor switch across a solid state laser. A second order filter, formed by the an external inductor and the output capacitance of the buck topology, minimizes AC current ripple to the laser.

摘要： An energy transfer device for solar power systems operates to draw power from high-producing photovoltaic devices and apply that power across low-producing photovoltaic devices. An embodiment is a self-regulating energy exchanger using bidirectional DC-DC converters that operates to maintain uniform voltage across each series-connected photovoltaic device. An alternative embodiment is an energy exchanger that is controlled to maintain each of several series-connected photovoltaic devices at a maximum power point by drawing power from high-performing devices and applying that power across low-performing devices to provide uniform current among series-connected photovoltaic devices.

摘要： An asymmetrical coupled inductor includes a first and a second winding and a core. The core is formed of a magnetic material and magnetically couples together the windings. The core is configured such that a leakage inductance value of the first winding is greater than a leakage inductance value of the second winding. The coupled inductor is included, for example, in a multi-phase DC-to-DC converter. A DC-to-DC converter including a symmetrical coupled inductor includes at least one additional inductor electrically coupled in series with one or more of the coupled inductor's windings. A controller for a DC-to-DC converter including a first phase having an effective inductance value greater than an effective inductance value of a second phase is configured to shut down the second phase while the first phase remains operational during a light load operating condition.

摘要： An electrosurgical system comprising, among other things, a control console to which detachably connects one or more electrosurgical probes capable of coagulating and ablating tissue. The control console generates a selectively variable power signal having a duty cycle that is dynamically modulated so as to maintain an average power level of a probe that is lower than a predefined maximum power level. The system can also incorporate both an impedance monitoring system and a current monitoring system as means to detect potentially dangerous situations, as well as a monitoring system for detecting impedance at relatively low power levels upon first activation of the probe. The probe can also incorporate non-volatile memory for storing probe-specific operating parameter data, probe usage data, data restricting probe use, error codes, and control console updates.
