12 ª 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 – high frequency generators – X-ray equipment – 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: – bridge circuit, B VdT = 0,9 x VV(RMS) – three phase bridge circuit, DB VdT = 1,35 = VV(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 – Hochfrequenz-Generatoren – Röntgenanlagen – elektrostatischen Staubfilteranlagen. Die Modulkonstruktion - Kunststoffgehäuse mit Schraub- verbindung - ermöglicht einen einfachen mechanischen Auf- bau der gewünschten Gleichrichterschaltung. Anwendungsspezifische Anschlußspannungen und Ströme können durch Auswahl der geeigneten Bausteine, Montage ohne und mit Kühlblech bei verschiedenen Kühlarten oder durch Serienschaltung verwirklicht werden. 2. Aufbau

2.1 Elektrisch

Hochspannungsgleichrichter-Module bestehen aus einer in- tegrierten Reihenschaltung von Avalanche-Dioden. Elektrische Anschlüsse der Modul-Schraubverbindung: Anode (A) = Gewindebohrung Kathode (K) = Gewindebolzen.

2.2 Mechanisch

(Abmessungen siehe Maßbild) In einem Epoxydharzbecher mit axial angeordneten Metallan- schlüssen sind die Avalanche-Dioden in Gießharz eingebettet. Die verwendeten Materialien garantieren eine gute Isolations- fähigkeit und Korrosionsbeständigkeit. 3. Technische Daten Die Betriebszuverlässigkeit von Hochspannungsgleichrichter- Modulen wird wesentlich durch den Sicherheitsabstand zwi- schen den angegebenen Grenzwerten und den Einsatzdaten beeinflußt. Für die spannungsmäßige Beanspruchung in Ein- zweigschaltung sind in der Tabelle Seite 3 Nennwerte - das sind empfohlene Betriebsdaten, die für sinusförmige 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: – Brückenschaltung, B VdT = 0,9 x VV(RMS) – Drehstrom-Brückenschaltung, DB VdT = 1,35 = VV(RMS)

Mounting instructions

5.1 Mounting of modules

without cooling plate (Fig. 7): 5. Montagehinweise

5.1 Darstellung der Montage:

Montage ohne Kühlblech (Bild 7)

5.2 Mounting of modules

with cooling plate: as shown in Fig. 7, however, the cooling plate ist mounted with thermal grease instead of with washer A 8.5 ∅ DIN 125. To satisfy VDE specification 0110, voltage limits are prescribed - depending on the creepage distance of the pot shape (61 mm for mounting without cooling plate, 42 mm for mounting with cooling plate). In case of air cooling care should be taken that the proper class of insulation is chosen for the respective supply voltage (see table 3).

5.2 Montage:

Module mit Kühlblech wie in Bild 7 skizziert, jedoch anstelle der Scheibe A 8,5 ∅ DIN 125 wird das Kühlblech mit Wärmeleitpaste eingesetzt. Zur Einhaltung der VDE-Vorschrift 0110 sind - bedingt durch den Kriechweg der Bechergeometrie (61 mm bei Montage ohne Kühlblech, 42 mm bei Montage mit Kühlblech) - Spannungs- grenzen vorgeschrieben. Zu beachten ist bei Betrieb in Luft, daß sich die zulässige Anschlußspannung nach der vorgese- henen Isolationsgruppe richtet (siehe Tabelle 3).

5.3 Distance to adjacent parts

The distance to adjacent g metal parts should be at least 25 mm. This also applies to mounting with cooling plates (see Fig. 8). A protective circuit in accordance with Table 4 should be provided in order to prevent unpermissible capacitive earth currents from flowing through the first diode. This can be done by arranging the modules in groups for voltages of Vp ~ 30 kV each (see Fig. 9).

5.3 Abstände zur Umgebung

Der Abstand zu umgebenden geerdeten Metall-T eilen sollte minimal 25 mm betragen. Dies gilt auch bei Aufbau mit Kühl- blechen (siehe Bild 8). Zur Vermeidung von unzulässigen kapazitiven Erdströmen über die erste Diode ist eine Schutzbeschaltung nach Tabelle 4 vor- zusehen. Es sind dabei jeweils Modulgruppen für Teilspannun- gen von Vp ~ 30 kV zu bilden (siehe Bild 9).
