Abstract

A device was composed of a trans. which had multi-coils(L1) which were independent from one another on the primary or secondary core and multi taps(T1-T6), a rotary S.W which had a plate (1) having multi fixed taps (T1'-T8') and a rotating connector. The device provides a const. output volt. according to various input volt. by rotating the S.W after changing the trans. and S.W. taps.
