  • Apparatus and method for soft switching in a medium voltage to low voltage converter
    Patent number: 8811038
    Abstract: A switching and control arrangement are provided along with a transformer arrangement such that semiconductor-based switches can be used in a medium DC voltage to AC inverter in a medium voltage to low voltage DC to DC converter. The switching arrangement on the secondary side of the transformer arrangement controls a current ramp up or down of switches on the primary side of the transformer that are used to convert DC to AC, thereby permitting for soft switching of those switches.
    Type: Grant

  • Method and system for improved thermal management of a voltage source inverter operating at low output frequency utilizing a zero vector modulation technique
    Publication number: 20050024902
    Abstract: The present invention includes a method for thermal management in a voltage source inverter. The method includes sensing a low output frequency condition, determining a zero vector modulation responsive to the sensed low output frequency condition, and applying the determined zero vector modulation to reduce thermal stress in the voltage source inverter. The step of determining the zero vector modulation responsive to the sensed low output frequency condition includes mapping an output voltage requirement to a space vector structure and determining state switching space vectors based on the mapped output voltage requirement.
