The present invention provides a reliable, high-repetition rate, production line compatible high energy photon source. A very hot plasma containing an active material is produced in vacuum chamber. The active material is an atomic element having an emission line within a desired extreme ultraviolet (EUV) range. A pulse power source comprising a charging capacitor and a magnetic compression circuit comprising a pulse transformer, provides electrical pulses having sufficient energy and electrical potential sufficient to produce the EUV light at an intermediate focus at rates in excess of 5 Watts. In preferred embodiments designed by Applicants in-band, EUV light energy at the intermediate focus is 45 Watts extendable to 105.8 Watts.

The invention mainly relates to an electronic device for voltage conversion. A second controller is used for sensing an output voltage or an output current of a secondary side of a transformer in real time for power switching so as to generate a transient response control signal, a coupling component is used for transmitting the control signal generated by the second controller to a first controller at a primary side, and the first controller is used for generating a first pulse signal for power switching so as to control switch-on or switch-off of a winding of the primary side.

The invention discloses a PWM type LED street lamp driver capable of saving half electric energy again and dissipating heat. A core technology is a pulse width adjustable automatic adjustment function or duty cycle adjustable square waves. By designing with a 555 time-base circuit and through changing charge-discharge loop parameters of the 555, the output square waves of the 555 are controlled; by employing the duty cycles of the different output square waves to control work of a field-effect transistor, a voltage output by a pulse transformer is controlled to be high and low, thereby controlling working condition transformation of a street lamp to be dazzling bright and dark bright and realizing an automatic light-adjusting function; with the automatic light-adjusting function, on the basis of energy saving of the street lamp, the energy is saved again for 50% or more; and a path of serial connection manner is adopted by a luminous panel circuit, and a rated current value of a single LED is used for driving the LED street lamp to work to control an LED working temperature of a lamp body to be 50 DEG C or below, so the service life of the LED street lamp is up to fifty thousand hours.
