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 ...

REO UK has refreshed REOVAR, a series of variable transformers that provide adjustable output voltages with a constant sinusoidal waveform. REOVAR is designed to eliminate high-frequency electrical ...

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: The dual-active-bridge (DAB)-based two-stage ac/dc converter is extensively applied in various scenarios, including electric vehicle chargers and solid-state transformers. In the two-stage ...
