#CMT# #/CMT# Method for controlling alternating voltage comprises using a secondary number of turns of a transformer which is proportional to the rotary angle of a controller and reversibly proportional to the potential difference along a turn. #CMT#USE : #/CMT# Method for controlling alternating voltage in an electronic device. #CMT#ADVANTAGE : #/CMT# The secondary number of turns of a transformer is reduced. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of the method. 1 : Transformer primary winding 2 : Transformer secondary winding 3 : Precision rectifier 6 : Potentiometer 8 : Analogue-digital converter. |
