  • Current control circuit and a method therefor
    Patent number: 10120429
    Abstract: A method and a current control circuit 100 therefor. The method for a current control circuit 100 comprising determining 201 a state of the current control circuit 100, select 202 a first mode of operation 203 if the determined state is a first state indicative of a hot plug-in of the input terminal 101 to a connectable DC voltage bus. The method further comprises selecting 202 a second mode of operation 204 if the determined state is a second state different from the first state. The method further comprises controlling 205 the output current using the selected mode of operation.

  • Electronic load module and a method and a system therefor
    Patent number: 9964598
    Abstract: The present invention relates to an electronic load module and to a method and a system therefor. The method comprises receiving control data (301) from a connectable power controller via a data bus connector (202), and controlling (302) an active load (203) based on the received control data to sink a defined current from a connectable device under test via a first input (204). The method further comprises controlling (303) the activate load (203) based on the received control data by means of a digital control circuit (201) and the connectable power controller to generate and maintain an ambient temperature of the device under test.
