Definitions

  • switching power supplies In order to stabilize the DC output voltage obtained in this way, such switching power supplies have a control loop which regulates the DC output voltage independently of a connected load to a constant value. This is possible by changing the frequency and / or the pulse width of the primary-side high-frequency AC voltage. As a result, the switching power supply only generates as much power as is passed on to the load. A switching power supply requires no complex secondary stabilization. In addition, smaller transformers can be used for switching power supplies, and their efficiency is very good.
  • a smoothing capacitor After rectifying an AC voltage into a pulsating DC voltage, a smoothing capacitor, usually an electrolytic capacitor, is used for smoothing and / or screening the pulsating DC voltage into a DC voltage of smaller ripple.
  • the required capacitance of the smoothing capacitor is determined essentially by the current to be supplied by the power supply. For a given output power, the smaller the voltage to be smoothed, for example the rectified input voltage of a wide-range power supply, the greater the current. Therefore, in a wide-range power supply, the capacitance of the smoothing capacitor is usually oriented to the capacitance needed for the lowest input voltage.
  • the voltage carrying capacity of the smoothing capacitor is determined by the largest permissible input voltage.
  • capacitors with a correspondingly high capacity and high voltage rating have a large size and are also expensive.
  • the object of the invention is to provide a power supply unit, in particular a wide-range power supply unit, which is considerably smaller with the same input AC voltage range.
  • the second smoothing capacitor has a larger capacity than the first smoothing capacitor.
  • the capacity of the adding smoothing capacitors below the threshold voltage is large.
  • a considerably smaller first smoothing capacitor is sufficient.
  • the capacitance of the first smoothing capacitor is about 5 to 20 ⁇ , more preferably about 10 ⁇ .
  • the capacitance of the second smoothing capacitor is preferably about 150-250 ⁇ , more preferably about 170-21 ⁇ .
  • Both power supplies are preferred in which the switching stage is arranged on the primary side, as well as those power supplies in which the switching stage is arranged on the secondary side.
  • power supplies are preferred which have both a first switching stage on the primary side, and a second switching stage on the secondary side.
  • Figure 1 is a schematic diagram of a trained as a switching power supply
  • FIG. 2 shows a schematic circuit diagram of a smoothing module according to the invention.
  • the switched-mode power supply 1 of FIG. 1 is provided for converting an input AC voltage UE into a DC output voltage UA. It has a transformer 5 with a primary side I and a secondary side I I.
  • a rectifier 2 is provided, with which the input AC voltage UE is converted into a pulsating DC voltage U1.
  • This is smoothed and / or screened in a smoothing assembly 3.
  • the smoothing subassembly 3 has a first smoothing capacitor C1.
  • the pulsating DC voltage U1 is converted into a DC voltage of lower ripple U2.
  • a switching stage 4 is also provided. With the switching stage 4, the DC voltage lower ripple U2 is converted into a higher frequency AC voltage U3.
  • the higher-frequency AC voltage U3 has a frequency which is significantly greater than the frequency of the input AC voltage UE.
  • the output voltage of the secondary-side smoothing module 7 is the DC output voltage UA of the power supply 1.
  • the output DC voltage UA is stable even when changing load 9
  • a control circuit 8 is provided with galvanic isolation, with which the frequency and / or the pulse width of the higher-frequency AC voltage U3 is adjustable.
  • the smoothing module 3 has, in addition to the first smoothing capacitor C1, a second smoothing capacitor C2.
  • the second smoothing capacitor C2 can be connected in parallel with the first smoothing capacitor C1 by means of an electrical switching module 33.
  • the second smoothing capacitor C2 is arranged parallel to the first smoothing capacitor C1.
  • the two smoothing capacitors C1, C2 are therefore each arranged in a shunt branch Q1, Q2 between two common supply lines Z1, Z2.
  • For parallel connection includes the electrical
  • Switching assembly 33 an electrical switch S, which is symbolically shown here, and which is arranged in the shunt branch Q2 of the second smoothing capacitor C2.
  • the switch assembly 33 is designed such that the electrical switch S closes or switches through when the pulsating DC voltage U1 at the first smoothing capacitor C1 falls below a threshold value. Above the threshold value, the electrical switch S is open, so that the electrical connection between the second smoothing capacitor C2 and the common supply line Z1 is interrupted. Only the first smoothing capacitor C1 must therefore have a high dielectric strength, since only at it the DC equivalent of the maximum provided AC input voltage can be present. The second smoothing capacitor C2, however, must be designed only for voltages below the threshold.
  • the capacitance of the smoothing assembly is the capacitance of the first smoothing capacitor C1.
  • the capacitances of the smoothing capacitors C1, C2 of the smoothing module 3 add up, so that the total capacitance is correspondingly greater.
  • a sufficiently large power can still be transmitted via the smoothing module 3.
  • the electrical switch S is preferably designed as a field-effect transistor, in particular as a low-resistance field-effect transistor. In principle, however, other electrical switches S, such as other transistors, relays, integrated switches or the like, can be used.
