Abstract

A passive integrated switching circuit, used to supply two distinct DC voltages from an AC 220V mains input has the building blocks handling the rectification, voltage limiting, smoothing all integrated with the two output stages. No transformer is used or needed. The electronic components involved are diodes, transistors, Zener diodes, plus resistors and capacitors. USE - For current supply systems.

Description

Der passive integrierte Schaltkreis GR 20/10 soll seine An­ wendung als Bauelement in der Stromversorgung finden.The passive integrated circuit GR 20/10 should start find application as a component in the power supply.

Der Schaltkreis besteht aus einer Gleichrichterschaltung, einer Spannungsbegrenzung, einer Glättungsschaltung und zwei Ausgangsstufen.( siehe Blockschaltung) Die Gleichrichterschaltung ist eine Brückenschaltung (siehe Innenschaltung). Sie bewirkt, daß sowohl die positive als auch die negative Halbwelle der Wechselspannung ausgenutzt wird.The circuit consists of a rectifier circuit, a voltage limit, a smoothing circuit and two Output stages (see block circuit) The rectifier circuit is a bridge circuit (see Internal circuit). It causes both the positive and the negative half-wave of the AC voltage is also used becomes.

Die Z-Dioden D6-D8 bilden mit einer in Reihe geschalteten Schutzdiode D5 die Spannungsbegrenzung. Mit deren Hilfe wird die Spannung auf einen bestimmten oberen Wert gehalten. Das ist z. B. bei integrierten Leistungsverstärkern wichtig, bei denen eine bestimmte Betriebsspannung nicht überschritten werden darf. Bei geringer Belastung oder Leerlauf steigt die Gleichspannung bekanntlich annähernd auf den Scheitelwert der Sekundärwechselspannung an. Die als Klemmdioden wirkenden Z-Dioden verhindern dies und halten die Ausgangsspannung unter der zulässigen Grenzspannung fest.The Zener diodes D6-D8 form with one connected in series Protection diode D5 the voltage limitation. With their help the voltage is kept at a certain upper value. The is z. B. important for integrated power amplifiers which do not exceed a certain operating voltage may be. With low load or idle the increases DC voltage is known to be approximately at the peak value of the Secondary AC voltage on. The act as clamping diodes Zener diodes prevent this and keep the output voltage under the permissible limit voltage.

Die Glättungsschaltung besteht aus einer pnp-Komplementär­ darlingtonstufe. Die Kapazität des an der Basis der Komple­ mentärstufe liegenden Kondensators C2 (siehe Anwenderschal­ tung) wird etwa mit dem Stromverstärkungsfaktor der Tran­ sistoren T1 und T2 multipliziert am Ausgang dieser Schaltung dynamisch wirksam. Setzt man eine Komplementärdarlington­ stufe ein, ist auch der erforderliche Spannungsabfall nur bis 1,5 V + UBR/2. Damit die in T1 auftretende Verlust­ leistung nicht zu groß wird, sollte die Brummspannung UBR eff 2 V bei max. Strombelastung nicht überschreiten. R1 und C2 bestimmen die Zeitkonstante des Siebgliedes. R1 wird durch die Stromverstärkung der Transistoren festge­ legt und kann deshalb nicht beliebig vergrößert werden. Bei Belastung des Netzteils wird die mittlere Ausgangs­ spannung dem jeweiligen Laststrom entsprechend niedriger. Die Ausgangsspannung ändert sich annähernd mit der Zeit­ konstante R1·C2. Schnellen Laständerungen kann die Schalt­ ung bei genügend großer RC-Konstante nicht folgen und wirkt deshalb ähnlich einem sehr großen Kondensators. Als Speicherkondensator wird jedoch nur die Kapazität von C2 wirksam, wobei die zur Verfügung stehende Spannung um den Betrag UBE T2 und dem Spannungsabfall über den nachgeschal­ teten Schutzdioden D9 parallel D10 und D11 niedriger ist. Diese Siebschaltung ist also kein Energiespeicher. Sie wirkt nur dynamisch als sehr großer Kondensator.The smoothing circuit consists of a pnp complementary darlington level. The capacity of the base at the comple capacitor C2 (see user scarf tion) is approximately with the current amplification factor of the trans sistors T1 and T2 multiplied at the output of this circuit  dynamically effective. If you put a complementary Darlington level, the required voltage drop is also only up to 1.5 V + UBR / 2. Hence the loss occurring in T1 power is not too high, the ripple voltage should UBR eff 2 V at max. Do not exceed current load. R1 and C2 determine the time constant of the sieve element. R1 is determined by the current amplification of the transistors sets and therefore cannot be enlarged arbitrarily. When the power supply is loaded, the middle output voltage corresponding to the respective load current lower. The output voltage changes approximately with time constant R1 · C2. The switching can cause rapid load changes not follow if the RC constant is large enough and therefore acts like a very large capacitor. When Storage capacitor, however, will only have the capacitance of C2 effective, the available voltage around the Amount UBE T2 and the voltage drop across the downstream tied protection diodes D9 in parallel D10 and D11 is lower. This filter circuit is therefore not an energy store. It works only dynamically as a very large capacitor.

Die Schutzdioden D9 bis D11 sollen Rückstrom von einem Ver­ stärkerüberbrückungskondensator über die Glättungsschaltung verhindern, wenn während des Ausschaltvorganges undefinierte Zustände eintreten. The protection diodes D9 to D11 should return current from a ver stronger bypass capacitor through the smoothing circuit prevent if undefined during the switch-off process States occur.
