A METHOD AND DEVICE FOR TRANSFORMING AND REGULATING A VOLTAGE SIGNAL

摘要

The present invention is generally directed to an efficient voltage transforming and regulating device based on a High Frequency (HF) transformer and a HF Electromagnetic Voltage Regulator (HFEVR) serially connected to the transformer's coil(s). The transforming and regulating device of the invention efficiently transforms and stabilizes an input power source without requiring filtering stages. The regulation of a voltage signal according to the present invention is carried out by utilizing one or more HFEVRs of the invention which comprise a coil magnetically coupled to an electromagnet, wherein said HFEVRs are connected to the primary and/or secondary coil(s) of a voltage transformer via their coils, and wherein the voltage over the primary and/or secondary coil(s) of said transformer is regulated by adjusting the value of the reactive resistance of said coils of said HFEVRs by suitable control signal provided to the their electromagnets.
