Abstract: PURPOSE:To obtain an output current of maximum permissible current value of winding or higher by a method wherein a voltage dividing tap, with which input voltage is outputted by stepping down, is provided on the primary winding of an insulating transformer which is also usable as a pressure divider, and a circuit, with which an output current will be obtained from the tap of the primary winding by changing-over a switch, is added. CONSTITUTION:Output terminals G and H are connected respectively to the taps A and B of the primary winding through the intermediary of switches SW1 and SW2 using the winding ratio of 1:1 of an insulating transformer T which is also used as a pressure divider. When the output current to be applied to output terminals E to F is set at i2, the current i1 flowing in the primary winding becomes i1=i2, therefore, the output of maximum allowable current value of the winding of the insulating transformer, which is usable as a voltage divider, can be obtained. Also, when the current flowing-in from the terminal A is set at ia, the output current ig to be applied to output terminals G to H becomes ig=ia-i1. As a result, the use of a thick wire material as an insulating transformer wire material to obtain a large current is unnecessitated.
