| 摘要 |
The invention relates to electronic transformers with input circuits and output circuits, which, along with the transformer function thereof, perform a power factor correction. Said transformers comprise a control circuit, which opens and closes an electronic switch, depending on the output voltage of the transformer circuit and the voltage occurring at a current measuring sensor. The invention is characterised, whereby the circuit comprises a logic mass LM and a power mass PM at different electrical potentials.
