Definitions

  • the invention relates to an inverter according to the preamble of claim 1, as it from the US Z .: C. M. Penalver, u. a. : Microprocessor Control of DC / AC Static Converters ", in: IEEE Transactions on Industrial Electronics, Vol. IE-32, No. 3, August 1985, pp. 186-191.
  • the conventional inverters have the following disadvantages: When using 50 Hz transformers, the devices are heavy and bulky. High losses occur when using HF transformers. A relatively high input voltage is required for circuits that do not use a transformer; the DC potential is not continuously at ground. When using thyristor inverters, the alternating current generated has relatively high distortion factors.

  • Fig. 1 shows the circuit diagram of such an inverter
  • FIG. 2 shows a switching pattern with which the semiconductor switches are switched depending on the profile of the AC voltage.
  • the circuit consists of a capacitor 34, which lies across the AC voltage inputs 12, 16.
  • a choke 8 is provided, one side of which is connected to the one DC voltage connection 12 via a first semiconductor 10 and the other side of which is connected to the other DC voltage input via a second semiconductor 14.

  • a - not shown - microcontroller switches the semiconductors 10, 14, 20, 26 and 32.
  • the first semiconductor 10 is only switched on and off several times during the positive half-wave of the sinusoidal mains voltage, and remains switched on during the negative half-wave.
  • the other semiconductor 14, on the other hand is constantly switched on and off, the ratio between the switch-on and switch-off times depending on the respective level of the mains voltage.
  • the third semiconductor 20 and the fifth semiconductor 32 are turned on during the positive half-wave and off during the negative half-wave. The reverse applies to the semiconductor 26.
  • the pulsed second semiconductor 14 applies a current to the inductor 8 during its conductive state, which current is taken from the DC voltage connections 12, 16 via the then closed semiconductor 10. Here, energy is stored in the throttle 8. If the second semiconductor 14 opens again, the energy stored in the choke 8 is fed to the AC voltage outputs via the first semiconductor 10 and the second series connection. This process is repeated in quick succession for the duration of the positive half-wave.
  • the energy stored in the inductor 8 during the negative half-wave after simultaneous blocking of the first and second semiconductors 10, 14 is obtained when the two semiconductors 14, 10 are simultaneously conducted via the first series circuit and the fourth semiconductor which is in series with the second diode 24 26 supplied to the AC voltage connections.

  • switching patterns with variable frequency such as occur in resonant converters, are also possible for the semiconductors 10 and 14.
  • the semiconductors 10 and 14 are either switched off or de-energized, which enables higher switching frequencies due to a lower loss line, and a reduced inductance 8. Small additional capacities or inductors enable this currentless or voltage-free switching.
  • the switching patterns for the semiconductors 10 and 14 differ in that the sum of the on and off times is no longer constant, i.e. the frequency of the pulse-modulated switching pattern is variable.
