POWER SUPPLY SOURCE FOR DEVICES WITH TWO POWER LEADS-IN Russian patent published in 1996 - IPC

FIELD: radio engineering. SUBSTANCE: proposed power supply source may be used to control any load. Source includes power high-voltage transformer which high-voltage winding leads are connected to input arms of three-phase bridge rectifier which minus lead-out is linked to one terminal of generator (for example, to cathode of magnetron) and which plus lead-out is connected through key element (for example thyristor or thyristor column) to other terminal of generator (for example, to lead-in of magnetron). One of high-voltage windings of transformer is supplemented with additional turns beyond limits of connection to input arm of rectifier. Lead from additional turns is connected through additional rectifying diode and second key element to connection point of first key element and lead of SHF generator (anode of magnetron). Instead of additional turns source may be inserted with high-potential transformer which primary winding is placed in circuit between zero wire and input terminal of one of primary windings of high-voltage transformer and which secondary winding is connected with one lead to lead-out of high-voltage winding of power transformer and with other lead through additional rectifying diode and second key element - to lead-out of SHF generator (for example, anode of magnetron). Low-capacity power supply source uses single-phase transformer which high-voltage winding has additional turns and capacitor is placed in parallel to rectifiers. In proposed source SHF generator works on practically constant voltage and indices of its efficiency, reliability and stability to overloads have maximum values. Source may be used in high-power industrial installations. EFFECT: increased operational characteristics of power supply source. 3 cl, 4 dwg
