Power converter with adjustable output voltage

摘要

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-regulating reactance and a current source. The second input terminal picks up a reference voltage. The voltage comparator has a first input terminal, a second input terminal and a compare output terminal. The compare output terminal is electrically connected to one terminal of a feedback reactance. The first input terminal is electrically connected to the other terminal of the feedback reactance and one terminal of a loading reactance. The other terminal of the loading reactance is electrically connected to the current source and one terminal of the voltage-regulating reactance. The other terminal of the voltage-regulating reactance is electrically connected to the positive voltage output terminal.
