  • Method and apparatus to remove energy from DC loads
    Patent number: 8004866
    Abstract: A DC output power converter or DC switch device that includes methods and apparatus to reverse the current in the connected load, thereby draining the load's energy until the voltage in the load is brought to a (near) zero potential and held there.
    Type: Grant
    Filed: December 30, 2008
    Date of Patent: August 23, 2011
    Assignee: Teknic, Inc.

  • Method and apparatus for protection of AC-DC power converters
    Patent number: 7911352
    Abstract: An AC-DC power converter controls an external upstream switching device, which supplies it power to be converted. Power conversion is initiated when an external signal requests power be converted or when a program within the AC-DC power converter detects the need for power conversion. When this occurs, the AC-DC power converter signals the external switching device, which is upstream of the AC-DC power converter to turn on, thereby supplying the power to be converted to the AC-DC power converter.

  • Method and Apparatus to Verify the Proper Connection of Loads before Applying Full DC Power
    Publication number: 20090174413
    Abstract: A DC power source or DC switching device that uses a test signal to verify the proper connection of the load (or loads) at its output prior to applying full power to the output. This method and apparatus inserts a low power or low energy test signal at the output terminals of a DC power source and measures the test signal's effect on connected external loads to access the condition and proper connection of these loads before applying full power to the DC output power port. If the test signal detects that a load is connected with a reverse polarity, is shorted, malfunctioning or can otherwise cause damage, it will inhibit the application of full power to the output terminals until the situation is corrected.
