  • Current Limited Power Converter Circuits And Methods
    Publication number: 20170331363
    Abstract: A power converter circuit regulates an output voltage of a power train circuit and controls the current in the power train circuit. A current sensor circuit measures a current in the power train circuit. A hysteretic comparison circuit compares the current in the power train circuit to positive and negative current limits. The hysteretic comparison circuit causes a positive current in the power train circuit to decrease in a positive current limit mode in response to the positive current in the power train circuit reaching the positive current limit. The hysteretic comparison circuit causes a negative current in the power train circuit to decrease in a negative current limit mode in response to the negative current in the power train circuit reaching the negative current limit. The hysteretic comparison circuit prevents a pulse width modulation controller from controlling the power train circuit during the positive and negative current limit modes.
