Means of providing variable reactive load capability on an electronic load

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.
