Abstract

PURPOSE: To obtain stable bipolar DC output, by using two sets of the regulators with the same type for two rectifying circuits obtaining plus and minus DC output.
CONSTITUTION: Two rectifying circuits 33 and 34 are connected to the secondary of the transformer 12, and one end of those output is taken as the intermediate tap 26 of the secondary coil of the transformer 12. Positive output is obtained to another end of the output side of the circuit 33 to the intermediate tap, and negative output is obtained at another end of the output side of the circuit 34 to the intermediate tap. Further,the output side obtaining positive output is connected to the input terminal 28 of the regulator 27, the common terminal is grounded, and the output terminal 35 is connected to the DC output terminal 16 at positive polarity. The tap 26 is connected to the input terminal 32 of the regulator 31, the common terminal 38 is connected to the output side where negative output of the circuit 34 is obtained and also to the negative DC output terminal 18, and the output terminal is grounded. As a result,stable bipolar DC output can be obtained.
