1 control transformer and the common principle of transformer without distinction,just use different, control transformer: a wide range of uses, can boost, or buckwith;
2 control transformer is the working principle of electromagnetic induction.Transformer with two groups of coils, the primary coil and the secondary coil. The secondary coil and the primary coil outside, when the current through the primary coil, transformer core produces alternating magnetic field, the secondary coilgenerates induction electromotive force. The number of turns of coil controltransformer ratio equal to the voltage ratio. For example: the primary winding is500 turns, the secondary coil is 250 turns, the primary through 220V alternating current, secondary voltage is 110V. Transformer step-down can also boost.
