Static Voltage Regulator With Automatic Bypass

Precision fast-PWM ac mains voltage correction

TSi Elecpower’s VRp is manufactured in a joint venture under license & technology transfer from TSi Power Corporation, USA. This automatic precision voltage regulator allows trouble-free operation of electronic equipment over a very wide mains ac voltage fluctuation range found in many developing countries. There is no switching of taps or otherwise a break in the power path thanks to continuous pulse-width-modulation (PWM) switching of a buck-boost transformer.
