An adjustable output voltage power converter. The power converter has a positive voltage output terminal, a negative voltage output terminal, a voltage comparator, a voltage shift resistor and a current source. The voltage comparator has a first input terminal, a second input terminal and a compare output terminal. The second input terminal picks up a reference voltage. The compare output terminal is electrically connected to one terminal of a Zf. The first input terminal is electrically connected to a second terminal of the Zf and one terminal of a Zi. The other terminal of the Zi is electrically connected to the current source and one terminal of the voltage shift resistor. The other terminal of the voltage shift resistor is electrically connected to the positive voltage output terminal.
