Insulated synchronous rectification dc/dc converter


When a pulse generator detects that a switching transistor on a primary side of a dc/dc converter turns off, the pulse generator sets a pulse signal s1 to an on level configured as an instruction to turn on a synchronous rectification transistor. When the pulse generator detects that the current that flows through the secondary winding of a transformer becomes substantially zero, the pulse generator sets the pulse signal s1 to an off level configured as an instruction to turn off the synchronous rectification transistor.

Device and optimizing diffusion section of electron beam


Provided is a device for optimizing a diffusion section of an electron beam, comprising two groups of permanent magnets, a magnetic field formed by the four magnetic poles extending the electron beam in a longitudinal direction, and compressing the electron beam in a transverse direction, so that the electron beam becomes an approximate ellipse; another magnetic field formed by the eight magnetic poles optimizing an edge of a dispersed electron-beam bunch into an approximate rectangle; by controlling the four longitudinal connection mechanisms so that the upper magnetic yoke and the lower magnetic yoke of the first group of permanent magnets move synchronously towards the center thereof thereby longitudinally compressing the electron beam in the shape of an approximate ellipse, and the upper magnetic yoke and the lower magnetic yoke of the second group of permanent magnets move synchronously towards the center thereof thereby longitudinally compressing the electron beam in the shape of an approximate rectangle, and the process of longitudinal compression is repeated until a longitudinal size of the electron-beam bunch is reduced to 80 mm. The invention is capable of reasonably compressing a longitudinal size of an electron-beam bunch after diffusion to approximately 80 mm, which ensures optimum irradiation uniformity and efficiency, and enables the longitudinal size to be within the range of a conventional titanium window,.
