  • Controlled holdup discharge for improved component reliability
    Patent number: 11095118
    Abstract: A method of controlling discharge of a holdup capacitor in a power system having a voltage source, a holdup capacitor and a load. The method including operably connecting the voltage source to the load, monitoring a first voltage of the voltage source, and if the first voltage of the voltage source drops below a selected threshold, directing energy from the holdup capacitor to the load via a first path, and directing energy from the holdup capacitor to the load via a second path if a selected condition is satisfied.
    Type: Grant
