BIPOLAR REGULATED DIRECT-CURRENT POWER SUPPLY

The proposed bipolar regulated direct-current power supply contains two constant-voltage regulators, a resistive transducer for measuring the difference between the load currents of the constant-voltage regulators, a semiconductor controlling element, current-limiting resistors and current-limiting transistors. The negative output terminal of the first constant-voltage regulator and the positive terminal of the second constant-voltage regulator are connected to the common point of the circuit and the common terminal of the proposed direct-current power supply via the resistive current difference transducer. The positive output terminal of the first constant-voltage regulator and the negative terminal of the second constant-voltage regulator are connected to the corresponding terminals of the proposed direct-current power supply via the current-limiting transistors and transistors. The semiconductor controlling element is inserted in the power supply circuit of the proposed direct-current power supply.
