Definitions

  • the invention describes a circuit arrangement for voltage regulation for generating a limited output voltage from an applied input voltage.
  • Such circuit arrangements are used when an uninterruptible power supply from any consumer is necessary, where the input voltage can exceed the maximum permissible operating voltage of the consumer.
  • Such circuit arrangements are required, for example, when the voltage rises during the charging process in battery-powered systems or when the voltage rises during the regenerative operation of a converter or during the so-called "load dump" in generator supply.
  • a Energy storage e.g. a capacitor or an accumulator.
  • a third possibility is so-called “clamping”, i.e. the use of special components such as. Zener diodes, varistors or suppressor diodes, which in the difference between the overvoltage and the maximum operating voltage contained energy Destroy conversion into heat. This is also the disadvantage of this possibility founded. Such components are limited in their power dissipation and are can only be used for short-term or low-energy overvoltages.
  • a fourth possibility is the use of series regulator circuits. These are both known as discrete as well as integrated circuits.
  • the disadvantage of Series regulator circuits is that they are also in the operating state in which the Value of the input voltage below the maximum permissible value of the operating voltage the consumer lies, have not inconsiderable power loss.
  • Even integrated Circuits with minimized losses, so-called “low-drop controllers” have one more Voltage drop of approx. 200mV across the component.
  • the present invention has the task of presenting a voltage control, the Losses in the presence of an input voltage less than or equal to the maximum permissible Operating voltage of the consumers are minimal, and their components and Circuit effort for the control when an input voltage is greater than maximum permissible operating voltage of the consumers are low.
  • a typical series regulator circuit 2 consists in its The simplest form of a transistor 24, a resistor 20 and a Zener diode 22.
  • the applied input voltage 6 becomes regulated via the transistor 24 Output voltage 8.
  • the series connection of the with the input (drain) acts as a control of the MOS-FET 24 connected resistor 20 with the zener diode 22, the anode the Zener diode with ground and the cathode of the Zener diode 22 with the control input (Gate) of the MOS-FET 24 are connected.
  • the series regulator circuit is expanded according to the invention by a clocked one Charge pump circuit 4, consisting in its simplest form of a resistor 40, a diode 46, a capacitor 42 and a clocked voltage source 44 is the output of transistor 24 with a series connection of resistor 40, Capacitor 42, the clocked voltage source 44 connected to a ground connection.
  • the anode of the diode 46 is at the midpoint between the resistor 40 and the Capacitor 42 connected while the cathode of diode 46 connected to the control input (Gate) of transistor 24 is connected.
  • Fig. 2 shows the inventive circuit arrangement (according to Fig. 1) supplemented by one additional switch, e.g. the transistor 12 to turn off the output voltage 8 can.
  • the collector of transistor 12 is connected to the gate of MOS-FET 24 connected.
  • Fig. 3 shows a variant of the inventive circuit arrangement (according to Fig. 2).
  • a regulated switching element 26 e.g. TL431 for controlling the Series regulator circuit used.
  • the necessary voltage input of the switching element 26 is formed by a voltage divider circuit made up of resistors 260 and 262.
  • the circuit arrangement shows a simulation of the functioning of the inventive circuit arrangement.
  • the basis of the simulation is a continuously increasing input voltage 50.
  • the curve 60 shows the output voltage of the inventive circuit arrangement, with a maximum Output voltage of 20V was approved.
  • Curve 70 shows the power loss of the inventive circuit arrangement.
  • the area 62 marks the work area of the Circuit arrangement in which the supply voltage is below the maximum permissible Value of the operating voltage of the consumer. In this area follows the course of the Output voltage 60 the course of the input voltage 50 with minimal losses 70.
  • the area 64 marks the working area of the circuit arrangement in which the Supply voltage above the maximum permissible value of the operating voltage of the Consumer lies.
  • the circuit arrangement works analogously Series regulator circuit according to the prior art with almost identical losses of two variants.
