Abstract: A driving circuit for controlling power of a light-emitting diode (LED) light source includes a transformer, a switch controller, and a dimming controller. The transformer has a primary winding that receives input power from an AC/DC converter and a secondary winding that provides output power to the LED light source. The switch controller coupled between an optical coupler and the primary winding receives a feedback signal indicative of a target level of a current flowing through the LED light source from the optical coupler, and controls input power to the primary winding according to the feedback signal. The dimming controller coupled to the secondary winding receives a switch monitoring signal indicative of an operation of a power switch coupled between an AC power source and the AC/DC converter, and regulates the output power by adjusting the feedback signal according to the switch monitoring signal.

Abstract: A system and method of controlling the primary switching FET turn-on and turn-off profiles in a switching power converter suppresses voltage and current spikes, reduces power consumption, and reduces system switching time. A combination of fast and slow shunt circuits is used to control current flow through the primary switching FET. The FET switching rate is slowed during the period of maximum current change to limit the magnitude of switching spikes and is allowed to proceed rapidly at other times to reduce switching time and power consumption.

Abstract: This invention comprises an improved electroporation electrode system comprising a single needle and a ring or donut shaped electrode wherein the difference in surface area of the electrodes provide for a substantial reduction of current density near the surface of the treated tissue and a more concentrated current density sufficient for electroporation only in tissues adjacent to the terminal portion of the single needle electrode. Thus, this invention provides for targeting specific tissue for electroporation and also should provide for lessening the sensation of electric current in the treated tissue.

Abstract: A controller for controlling power to a light source includes a first sensing pin, a second sensing pin, a third sensing pin, and a driving pin. The first sensing pin receives a first signal indicating an instant current flowing through an energy storage element. The second sensing pin receives a second signal indicating an average current flowing through the energy storage element. The third sensing pin receives a third signal indicating whether the instant current decreases to a predetermined current level. The driving pin provides a driving signal to a switch to control an average current flowing through the light source to a target current level. The driving signal is generated based on one or more signals selected from the first signal, the second signal and the third signal.

Abstract: A method and apparatus of primary side output voltage sensing for a flyback power converter preserves secondary-side tranformer isolation without the use of opto-isolators and does not require multiple high-speed sample and hold circuits. A timing circuit measures the duration of the diode conduction interval during a first PWM control cycle and applies this measurement to set the voltage sampling time of the feedback loop during the next PWM cycle. The voltage sampling time for the next PWM cycle is configurable and may be set to occur near the middle of the diode conduction interval or near the end of the diode conduction interval. The cycle-to-cycle PWM duty cycle adjustment step size may be limited to ensure that the diode conduction interval does not vary substantially from cycle to cycle.
