摘要： In an autotransformer of a single-phase three-wire system or a single-phase two-wire system, plural sets of main coils connected with input terminals are phase-wound on a single-phase core-type core, and further, between the ends of the main coils, plural sets of excitation coils mutually connected in series to wind on the single-phase core-type core are connected by plural combined connections. Further, plural sets of thyristors controlled ON/OFF by using the value measured by a voltage sensor connected to the aforementioned input terminals are provided between the aforementioned ends and the exciting coils. Therefore, the circuits are automatically changed in response to the increase and decrease of the input voltage, with a result that a load is not ill influenced so that the voltage value is always output within the predetermined range.
