Patent Images
1. An electric adjuster, comprising:
- a transformer having one secondary winding and a plurality of primary windings the numbers of windings of which are twice, four times, eight times, . . . 2n-1 times as much as the smallest number of winding ( n is the number of the primary windings), respectively, said secondary winding having an output terminal providing an output voltage; and
winding switching operation means for automatically switching the combinations of connections of the respective primary windings to adjust the number of composite primary windings in response to the output voltage provided by said output terminal to adjust the output voltage to become constant.

Abstract
An electric adjuster is so designed that, in order that an a.c. power supply or an a.c. signal as an input is arbitrarily adjusted or converted with high efficiency and outputted, the ratio of winding of a transformer can be arbitrarily adjusted or continuously adjusted. Thus the output voltage is automatically adjusted to become constant.
