McNeill, John A.
A prototype instrument has been developed which is capable of providing a transient current of up to 50A with a rise time as low as 1[mu]sec. This instrument, which simulates the transient current loads drawn by a high-speed microprocessor, allows measurement of the transient performance of switch-mode power supplies designed for use in PC systems. The minimum current, maximum current, and rise time are digitally programmable. The frequency and duty cycle of the load transient waveform is determined by a digital input signal.
