More complex arrangements are practical where precise voltage regulation is required.
The onboard voltage regulation was typically performed by devices of the 78xx family (for example, a 7805 device to produce +5 volts).
The computer contained internal voltage regulation against power line variations of voltages from 95 to 130 volts.
The three active units are used for voltage regulation.
The third brush dynamo had the advantage of simplicity but, by modern standards, it gave poor voltage regulation.
Other important factors are, for example, voltage regulation and number of connectors.
This means, a transformer with a variable turns ratio is produced, enabling voltage regulation of the output.
For the first time in German locomotives high voltage regulation of the transformer was used in serial production.
The quality of a system's voltage regulation is described by three main parameters:
A new generation of devices for voltage regulation based on solid-state technology are in the early commercialization stages.
