Abstract

A distribution network simulator is inserted in the sense lead circuitry of a power supply under test. This allows the dummy load to be connected directly to the power supply terminals, as distinguished from other test systems where it is customary to connect the distributing network simulator between the dummy load and the power supply terminals. Distribution network simulator circuit 1, which is of the two-port RC or RLC type, is connected between the sense lead probes 2-3 and the dummy load L. Probes 2-3 are connected to the sense lead terminals 5-6 of the power supply 4 being tested. The circuit 1 is connected across dummy load L, and the load L is connected directly across the power supply terminals 7-8 of power supply 4.

Distribution Network Simulator for Testing Power Supplies

A distribution network simulator is inserted in the sense lead circuitry of a power supply under test. This allows the dummy load to be connected directly to the power supply terminals, as distinguished from other test systems where it is customary to connect the distributing network simulator between the dummy load and the power supply terminals. Distribution network simulator circuit 1, which is of the two-port RC or RLC type, is connected between the sense lead probes 2-3 and the dummy load L. Probes 2-3 are connected to the sense lead terminals 5- 6 of the power supply 4 being tested. The circuit 1 is connected across dummy load L, and the load L is connected directly across the power supply terminals 7- 8 of power supply 4. Network 1 is adjusted to simulate different transfer functions which are associated with different power supply and distribution/load systems, as may be encountered in the field because of, for example, different lengths and/or sizes of the distribution leads. Because of its location, circuit 1 uses small low-power components and is more readily interchangeable in the present power supply test system, then is the case of the other aforementioned test systems which use bulky and high-power component distribution network simulators that are connected to the power supply terminals.
