Electronicly controlled isolating autotransformer
MetadataShow full item record
The goal of this work was to build a universal fully controllable laboratory power supply with AC output voltage. Main emphasis has been put on the final quality and durability of the power supply. Output voltage regulation is based on the principle of serial switching of secondary windings. The intelligent microprocessor control with alphanumeric display is also integrated in power supply. Realized power supply is suitable for universal applications, not only in electrical laboratories. Three fuses, electronic current and voltage limiters allow usage of this power supply also in school laboratories. The galvanic isolation is provided by a safety isolation of main transformers.
