    Abstract: A method of controlling a flyback DC-DC converter includes using a primary control loop to monitor an auxiliary winding of a transformer for determining the amount of energy being transferred to a load. The voltage in the auxiliary winding is induced by current flowing in the secondary winding of the transformer. The primary control loop disables and enables the turning on of a power switch for driving the primary winding of the transformer, and detects the zero-crossing. The duration that the power switch is turned on is established by a secondary control loop using the output voltage for turning off the power switch for a new off phase. The flyback DC-DC converter further includes a fixed frequency oscillator having a frequency lower than the self-oscillating frequency of the converter. The power transferred from the primary circuit to the secondary circuit of the flyback transformer is controlled by introducing a delay on the turn-on instant of the power switch. This is with respect to a turn-on command generated during a self-oscillating functioning phase regardless of the mode of control of the converter. The turn-on command is based upon a zero crossing, a fixed frequency functioning phase, a rising edge of the signal generated by the oscillator, and as a function of the input variables of the primary and secondary control loops.

    Abstract: Described herein is an optically controlled electrical-switch device which includes a first current-conduction terminal and a second current-conduction terminal, and a carbon nanotube connected between the first and the second current-conduction terminals, the carbon nanotube being designed to be impinged upon by electromagnetic radiation and having an electrical conductivity that can be varied by varying the polarization of the electromagnetic radiation incident thereon. In particular, the carbon nanotube may for example, in given conditions of electrical biasing, present a high electrical conductivity when it is impinged upon by electromagnetic radiation having a given wavelength and a polarization substantially parallel to the axis of the carbon nanotube itself, and a reduced electrical conductivity when it is impinged upon by electromagnetic radiation having a given wavelength and a polarization substantially orthogonal to the axis of the carbon nanotube itself.
