Power Saver consisted of Electronic Auto Transformer and Standby Power Breaker with Power Switching Semiconductor

摘要

The subject innovation is, by selectively combining connected to the cross-winding direction to apply a power switching semiconductor device such as an inter-series winding, and shunt winding of the electronic automatic autotransformer as a triac, SCR quickly enter under a stable environment that does not generate an arc of high energy perform the step-down or step-up operation of the voltage will be the provision of power jeolgamgi consisting of electronic autotransformer automatically applying the power switching semiconductor device for supplying a driving voltage of a minimum guaranteed load equipment normally for that purpose.; Devised] To achieve the above object, a voltage transformer unit which the voltage is applied to the input terminal a voltage value corresponding thereto to step-down (or boosting) supplied to the output terminal of the reference value or more (or less), is composed of the series winding, and shunt winding is provided by applying an autotransformer, and a power switching semiconductor device, such as between the series winding, and shunt winding of the autotransformer as a triac, SCR, which is installed between the input terminal and an output terminal includes a coil connection portion for connecting the series winding, and shunt winding and the voltage transformer unit step-down depending on the voltage value detected by the input stage (or step-up) so that the control unit for controlling the said voltage the series winding for the step-down or step-up in the transformer unit and shunt according to a detected voltage value from the input terminal to control the coil connecting portion to selectively connect the combination with the cross-winding direction of the winding It provides a power jeolgamgi consisting of electronic autotransformer automatically applying the power switching semiconductor device according to claim.
