ABSTRACT:
A circulating load apparatus for loading a power supply. The power supply has a power input terminal, a power output terminal and a power return terminal. The power supply provides an output voltage at the power output terminal with respect to the power return terminal. The output voltage of the power supply is controlled to be substantially identical in amplitude to the network voltage of a network source, provided at a network source terminal with respect to a source return terminal. The power supply, power return terminal is coupled to the network source, source return terminal. The power supply power input terminal is coupled to the network source terminal to be powered by voltage and current from the network source terminal. The circulating load apparatus has a voltage source for supplying a voltage between a first and second terminal. The voltage source is connected in series between the network source terminal and the power supply power output terminal. The output voltage of the power supply and the voltage source add to provide output power to the network source. An adjusting circuit adjusts the voltage of the voltage source to position the output current of the power supply within a predetermined range to deliver power from the power supply to the network source.
