Abstract
A constant-voltage generating apparatus including a plurality of constant-voltage circuits connected in series is provided. Each of the constant-voltage circuits has a positive-side power supply node, a negative-side power supply node, and a control unit that controls voltage between the positive-side power supply node and the negative-side power supply node to be constant voltage. The positive-side power supply node in the constant-voltage circuit at a preceding stage is connected to the negative-side power supply node in the constant-voltage circuit at a subsequent stage. The constant-voltage generating apparatus may further include a constant-current circuit that regulates power-supply currents flowing through the plurality of constant-voltage circuits to be constant.
