Abstract
A high power source load simulator presents itself to a power meter as a conventional electrical load, but in fact is highly portable and dissipates relatively little power and heat. A current source generates a selectively variable current signal which is characterized by a relatively low, constant voltage. A voltage source generates a selectively variable voltage signal which is phase locked with the current signal and is characterized by a relatively low, constant current. The phase angle between the two signals is selectively variable by means of a phase shift network interposed mediate the voltage and current sources. The current and voltage signals are impressed upon the current and voltage sensing inputs of a power monitor via jumper cables. An AGC circuit is also interposed between the voltage and current sources to insure the amplitude independence of their respective signals.
