  • Multi-voltage capacitive filter protection circuit
    Patent number: 12476452
    Abstract: A protection circuit for a capacitive filter for a multi-voltage system includes a first capacitor electrically connected between a first connection point at a first electrical potential and a second connection point at a second electrical potential and a second capacitor electrically connected between the second connection point and a third connection point at a third electrical potential. The first electrical potential is greater than the second electrical potential and the third electrical potential is less than the second electrical potential. The third electrical potential may be electrical ground. A controller circuit monitors a voltage differential across the first capacitor and the second capacitor and, based on the voltage differential meeting a threshold condition, controls a switch to disconnect one or both of the first capacitor and the second capacitor.
