Abstract

The switched mode supply stage has a regulated primary circuit in which a demand value is specified as a control parameter using parameters of a secondary circuit. The demand value is smoothed or held constant over at least one mains cycle and taken into account in the control parameter for the primary circuit current and voltage.

Description

Allgemeine RandbedingungenGeneral boundary conditions

Zum 1. 1. 2001 wurden neue Grenzwerte für die Netzrückwirkung von elektrischen Geräten festgelegt. Die Anforderungen an Vorschaltgeräte (EVG) für Leuchten sind dabei gegenüber der Vergangenheit erheblich verschärft und führen isbs. für die Versorgung von Leuchtdioden als Leuchtmittel bei Anwen­ dung konventioneller Schaltungstechniken zu einem deutlichen Mehraufwand.As of January 1, 2001, new limit values for the retroactive effect of electrical devices were set. The requirements for ballasts (EVG) for luminaires are compared to the past significantly tightened and lead to isbs. for the supply of light-emitting diodes as illuminants for users conventional circuit technologies at a significant additional cost.

Diese Anforderungen sind festgelegt in der Norm EN 61000-3-2 gemäß Klasse D (bis 25 W Leistung) und Klasse C (von 25 W bis 1000 W).These requirements are defined in the standard EN 61000-3-2 according to class D (up to 25 W power) and class C (from 25 W to 1000 W).

Lösungsansatzapproach

Die technische Lösung des Schaltnetzteils ist dadurch gekennzeichnet, dass die Regelkreis-Rückfüh­ rung zwischen dem Optokopper der Sekundärseite und dem Regler der Primärseite aufgetrennt wird und durch eine PFC-Regelung mit speziellen Eigenschaften erweitert wird. Diese PFC-Regelung verwendet dabei zunächst die nachfolgend beschriebenen Signale als Regelgrössen:
a) Signal Optokoppler-Rückführung (Signal D)
Das Ausgangssignals des Netzteils besitzt eine rel. hohe Restwelligkeit. Dieses Signal wird über den Optokoppler in Form von 100 Hz-Impulen zurückgeführt und mit der Zeitkonstante von ca. 1 s inte­ griert. Damit gewinnt man am Ausgang des Integrators ein Gleichspannungssignal, das sich proportional zur am Ausgang angeschlossenen Last verhält.
b) Strom-Sollwert (Signal A)
Dieser zweite Sollwert der Regelung wird am Ausgang der Gleichrichterbrücke abgegriffen und liefert den Sollwert für den Eingangsstrom des Schaltnetzteils.The technical solution of the switching power supply is characterized in that the control loop feedback between the optocoupler on the secondary side and the controller on the primary side is separated and expanded by a PFC control with special properties. This PFC control initially uses the signals described below as control variables:
a) Signal optocoupler feedback (signal D)
The output signal of the power supply has a rel. high ripple. This signal is fed back via the optocoupler in the form of 100 Hz pulses and integrated with the time constant of approx. 1 s. This provides a DC voltage signal at the output of the integrator that is proportional to the load connected to the output.
b) Current setpoint (signal A)
This second setpoint of the control is tapped at the output of the rectifier bridge and supplies the setpoint for the input current of the switching power supply.

Beide Signale aus a) und b) werden über einen Summierer zusammengeführt. Am Ausgang steht damit ein Signal zur Verfügung, das die zeitabhängige Regelabweichung zwischen Sollwertvorgabe am Eingang und ISTwert am Ausgang des Netzteils enthält. Diesem Signal wiederum wird über einen weiteren Summierer der Strom-Istwert (Signal B) des Schaltnetzteil-Eingangs (Shunt-Widerstand) zugeführt. Das resultierende Differenzsignal (Signal C) dient als Eingangssignal für den Schaltregler.Both signals from a) and b) are combined via a summer. At the exit thus a signal is available that shows the time-dependent control deviation between the setpoint at the input and actual value at the output of the power supply. This signal in turn is transmitted via a further totalizer the actual current value (signal B) of the switching power supply input (shunt resistor) fed. The resulting difference signal (signal C) serves as an input signal for the switching regulator.

Sonstige Besonderheiten der SchaltungOther special features of the circuit

Der Kondensator CP' ist mit ca. 0,2 mikroF gegenüber der Standardauslegung von ca. < 5 mikroF deutlich kleiner ausgelegt. Der Siebelko CS' hinter dem Übertrager auf der Sekundärseite ist mit ca. 4000 mikroF im Gegensatz zur Standardauslegung von ca. 100 mikroF deutlich grösser ausgelegt.The capacitor CP 'is approximately 0.2 microF compared to the standard design of approximately <5 microF designed significantly smaller. The Siebelko CS 'behind the transformer on the secondary side is approx. 4000 mikroF in contrast to the standard design of approx. 100 mikroF designed significantly larger.

Wirkungsweiseoperation

Durch die entsprechende Auslegung der Regelzeitkonstanten, insbesondere die Dimensionierung der Kondensatoren (CP' = ca. 0,2 mikroF und CS' = ca. 4000 mikroF) wird auf Basis des beschriebenen Regelungskonzeptes sicher gestellt, dass insbesondere die Anforderungen der EN61000-3-2 erfüllt werden.By appropriately interpreting the control time constants, in particular the dimensioning of the Capacitors (CP '= approximately 0.2 microF and CS' = approximately 4000 microF) is described on the basis of the Control concept ensures that in particular the requirements of EN61000-3-2 are met become.

Die Reduzierung unter die geforderten Maximalwerte der jeweiligen Oberwellenanteile gemäß EN 61000-3-2 ist dabei eine Frage der Dimensionierung der für das Regelverhaltens bestimmenden Bauteile der Schaltung. Dies sind neben dem Schaltungsprinzip unter Verwendung der beschriebenen Regelkenngrößen und der Reihenschaltung von Intergrierern und Summierern insbesondere die Dimensionierung der Ladekondensatoren CP' (Primärseite) und CS' (Sekundärseite).The reduction below the required maximum values of the respective harmonic components according to EN 61000-3-2 is a question of dimensioning the ones that determine the control behavior Components of the circuit. In addition to the circuit principle, these are described using the Control parameters and the series connection of integrators and summers, in particular the Dimensioning of the charging capacitors CP '(primary side) and CS' (secondary side).
