Means of providing variable reactive load capability on an electronic load
First Claim
1. A method for providing variable reactive load capability on an electronic load, the method comprising:
- receiving a latency value through a user interface of the electronic load;
receiving an input signal at one or more input terminals of the electronic load;
sensing a voltage of the input signal;
adjusting, using a power dissipating element, a current of the input signal from a first current value to a second current value in response to the sensed voltage; and
creating a delay based on the latency value input through the user interface between the time that the voltage of the input signal is sensed and the time that the power dissipating element adjusts the current to the second current value.

Abstract
Embodiments of the invention include an electronic load having variable reactive load capability and techniques for controlling and/or modeling a reactive component in a load. The electronic load can include a user interface through which a latency value is received from a user. A delay is created based on the latency value between the time that a variable of the input signal is sensed and the time that a variable of the input signal is driven to a new value, thereby simulating a reactive component in the electronic load based on the created delay. In one example embodiment, the driven variable can be stepped after the created delay to produce an approximation of a capacitive or inductive element. In another example embodiment, the driven variable can be slewed during the delay period using an arbitrary waveform generator, thereby more accurately simulating the reactive component.
