Solid-state ac supplies replace motor-generator and tap-changing transformers to offer the same tests at the push of a button • Solid-state ac-power sources combine the variable-frequency and ...

Abstract: Usually electric power transmission and distribution are using alternating current (AC). One of many important tools that have been used for electric power distribution are Transformer. In ...

Abstract: This paper presents a thyristor-based tap changing transformer and diode rectifier for variable-voltage high-current DC applications. Back to back thyristors are connected in series with the ...
