1. A power source circuit comprising a first source section for generating a first voltage source having a first polarity, a second source section for generating a second voltage source having a second polarity opposing said first polarity, an impedance converter for receiving said second voltage source to generate a third voltage source having an output impedance different from an output impedance of said first voltage source, a first voltage divider for dividing a voltage difference between said third voltage source and said first voltage source to generate a first divided voltage having said second polarity, and a control unit for controlling a voltage of said first voltage source by maintaining said first divided voltage at a first reference voltage.
