Abstract

Beschrieben wird eine Schaltungsanordnung zum Liefern wenigstens zweier voneinander abhängiger Speisespannungen (Ua1, Ua2, ..., Uan) aus einer Versorgungsspannung (Uv), mit

  • einer ersten Regelstufe (8) zum Regeln des Istwertes einer ersten (Ua1) der Speisespannungen auf einen zwischen einem ersten oberen und einem ersten unteren Toleranzgrenzwert einstellbaren ersten Sollwert sowie
  • wenigstens einer weiteren Regelstufe (9, 10) zum Regeln des Istwertes je einer weiteren der Speisespannungen (Ua2, ..., Uan) auf je einen vorzugsweise innerhalb eines Bereiches zwischen je einem weiteren oberen und einem weiteren unteren Toleranzgrenzwert einstellbaren weiteren Sollwert durch Verändern des ersten Sollwertes im Bereich zwischen dem ersten oberen und dem ersten unteren Toleranzgrenzwert nach Maßgabe von aus Vergleichen zwischen den Istwerten der weiteren Speisespannungen (Ua2, ..., Uan) und den zugehörigen weiteren Sollwerten in den zugeordneten Regelstufen (9, 10) gewonnenen Stellsignalen (auf 15, 16).
A circuit arrangement for supplying at least two interdependent supply voltages (Ua1, Ua2, ..., Uan) from a supply voltage (Uv) is also described
  • a first control stage (8) for regulating the actual value of a first (Ua1) of the supply voltages to a first setpoint value which can be set between a first upper and a first lower tolerance limit value and
  • at least one further control stage (9, 10) for regulating the actual value of a further one of the supply voltages (Ua2, ..., Uan) to a further desired value which can preferably be set within a range between a further upper and a further lower tolerance limit value by changing the first setpoint in the range between the first upper and the first lower tolerance limit value in accordance with control signals obtained from comparisons between the actual values of the further supply voltages (Ua2, ..., Uan) and the associated further setpoints in the assigned control stages (9, 10) on 15, 16).

Dadurch wird bei vereinfachtem Schaltungsaufbau eine bessere Genauigkeit der Speisespannungen auch unter Last erhalten.
