Definitions
- the main innovation is, in excerpts shown in Fig. 1, described.
- mains-controlled circuit breakers such as zero-voltage switches or antiparallel thyristors via a suitable control matrix and by the low-voltage (6, 9, 11 V) high-current windings connected in series to the distributor transformer phase
- the actual current value can be determined Phase voltage in the percentage range steer / regulate.
- transformers 2 and 3 are set to 230 / 9.2 V, the increments + 8%, + 4%, 0%, - 4%, - 8% for the load voltage change can be achieved.
- the single-phase inverter shown in FIG. 2 must be hardware-wise designed to provide a low input voltage to the secondary winding of the distribution transformer, e.g. 207 V, can convert into an at least 230 V output voltage for the supply of the additional transformer at the same frequency.
- Telecontrol e.g. Powerline modems
- Powerline modems Telecontrol, e.g. Powerline modems
- the bypass shown in FIG. 2, which lies parallel to the primary winding of the additional transformer, has the task of preventing the occurrence of overcurrents in the distribution network, e.g. resulting short circuit to protect the primary winding of the auxiliary transformer from breakdown.
- the bidirectional required inverter does not need to be oversized unnecessarily (cost).
- the arrangement shown in Fig. 2 only for one phase of the consumer three-voltage network must be realized three times.
- a summary of a three-phase system of three single-phase transformers and three single-phase inverters is not recommended because of the different load cases per phase in the three-phase consumer network.
- the controller can be supplied with analogue (bipolar analog size for regulation higher and lower), pure digital (higher / lower stepped) or analog / digital (unipolar analog variable for control / sign for higher and lower).
- the distribution transformer is in the nominal case per phase
- the auxiliary transformer must be able to handle the same power.
- FIG. 1 shows a single-phase circuit diagram of a regulated local power transformer with two additional transformers connected downstream, each having a primary winding.
- Fig. 2 shows an inventive circuit diagram with an additional transformer and a bidirectional inverter.
- FIG. 1 shows a structure with two additional transformers each having a primary winding and a corresponding number of electronic switches V v .
- Short-circuiting of a phase means that on the secondary side of each transformer, n times the rated current (n to 25 depending on the short-circuit voltage) flows, which leads to a considerable increase of the primary voltages.
- the windings Ni are designed for 230V rated voltage, through N 3 for 9.2V (equivalent to 4%).

- Fig. 2 an embodiment of the invention according to the description is shown, in which a distribution transformer 3, an additional transformer 2 is connected downstream, wherein the secondary winding 4 of the auxiliary transformer 2 is connected to the distribution transformer 3 in series.
- the primary side 5 of the additional transformer 2 is mains-powered and equipped with an upstream bidirectional inverter 6, which operates controlled with a controller 7 as a boost converter or step-down converter, whereby a continuous adjustment of the voltage applied to the primary side 5 of Rajtrafos2 voltage is reached.
- a controller 7 as a boost converter or step-down converter
- the controller 7, the target and actual voltage is supplied.
- the actual voltage is adjusted or tracked with respect to the setpoint voltage by the control of the inverter 6.
