Observing the Step Load Response of a Power Supply

After checking the gain and phase margin of a power supply control loop, observing the response of the supply to a step load change lets you watch the control loop in action. In this example, a pulse from the oscilloscope’s built-in function generator is input to an active current injector from Picotest to apply step changes to the demand on a power supply.
