1. A method for testing an AC power source by simulating a load with desired characteristics, comprising the steps of:

  • in response to user input signals and in response to a product of load current signals and load voltage signals, said user input signals corresponding to said desired characteristics of said load to be simulated, providing first control signals and second control signals;

    simulating a first set of load characteristics by rectifying power provided by said AC power source in response to said first control signals;

    simulating a second set of load characteristics by a load bank in response to said second control signals;

    providing said load current signals in response to current drawn by said load bank;

    providing said load voltage signals in response to the voltage across said load bank;

    reading a set of characteristics of said AC power source;

    computing load power; and

    determining whether said computed load power is within predetermined limits.
