12 ? 1997 ixys all rights reserved 1. general remarks the high-voltage retifier modules of the uge series function as single-leg half-wave rectifiers (abbreviation = e). they are used for high-voltage dc supply, e.g. in C high frequency generators C x-ray equipment C dust precipitators. the construction of the module plastic case with screw connection simplifies mechanical arrangement of the desired rectifier circuit. the user's individual input voltage and current requirements can be satisfied by selection of the appropriate modules, by mounting with or without a cooling plate or by series connection of modules. 2. design 2.1 electrical high-voltage rectifier modules consist of an internally integrated series connection of avalanche diodes. electric terminals of the module screw connection: anode (a) = threaded hole cathode (k) = threaded bolt 2.2 mechanical (for dimensions see dimension diagram) the avalanche diodes are embedded in an epoxy resin pot with axial metal terminals. the materials used guarantee good insulation and resistance to corrosion. 3. technical data the operating reliability of high-voltage rectifier modules is mainly influenced by the safety margin between the specified limit values and the operating data. table on page 3 gives rated voltage values - recommended voltages with a frequency of 40 to 60 hz and a maximum voltage variation of 10% - for the single leg circuit configuration. when other rectifier circuits are arranged with these modules v dt becomes: C bridge circuit, b v dt = 0,9 x v v(rms) C three phase bridge circuit, db v dt = 1,35 = v v(rms) 1. allgemeines die hochspannungsgleichrichter-module der serie uge sind in ihrer elektrischen funktion einweggleichrichter in einzweig- schaltung (kurzbezeichnung = e). sie werden zur hoch- spannungs-gleichstromversorgung eingesetzt, z.b. in C hochfrequenz-generatoren C r?ntgenanlagen C elektrostatischen staubfilteranlagen. die modulkonstruktion - kunststoffgeh?use mit schraub- verbindung - erm?glicht einen einfachen mechanischen auf- bau der gewnschten gleichrichterschaltung. anwendungsspezifische anschlu?spannungen und str?me k?nnen durch auswahl der geeigneten bausteine, montage ohne und mit khlblech bei verschiedenen khlarten oder durch serienschaltung verwirklicht werden. 2. aufbau 2.1 elektrisch hochspannungsgleichrichter-module bestehen aus einer in- tegrierten reihenschaltung von avalanche-dioden. elektrische anschlsse der modul-schraubverbindung: anode (a) = gewindebohrung kathode (k) = gewindebolzen. 2.2 mechanisch (abmessungen siehe ma?bild) in einem epoxydharzbecher mit axial angeordneten metallan- schlssen sind die avalanche-dioden in gie?harz eingebettet. die verwendeten materialien garantieren eine gute isolations- f?higkeit und korrosionsbest?ndigkeit. 3. technische daten die betriebszuverl?ssigkeit von hochspannungsgleichrichter- modulen wird wesentlich durch den sicherheitsabstand zwi- schen den angegebenen grenzwerten und den einsatzdaten beeinflu?t. fr die spannungsm??ige beanspruchung in ein- zweigschaltung sind in der tabelle seite 3 nennwerte - das sind empfohlene betriebsdaten, die fr sinusf?rmige ver- sorgungsspannung von 40 bis 60 hz und maximal 10% spannungsschwankung gelten - angegeben. bei aufbau von anderen gleichrichterschaltungen mit diesen modulen ergibt sich v dt entsprechen: C brckenschaltung, b v dt = 0,9 x v v(rms) C drehstrom-brckenschaltung, db v dt = 1,35 = v v(rms)
