Functional ATE and Power Supply Test
Solution Briefs
Power supply testing has become increasingly demanding, especially for military power supplies. Most power supplies today require communications, programming and more sophisticated testing, such as inserting ripple on DC inputs and measuring power supply rejection. Other tests include differential measurement of low amplitude ripple and noise at high frequencies in a high common-mode environment. Most power supplies require a combination of AC and DC source inputs from 3 to 30 KW with low noise outputs.
The test fixtures need to have break-out test points for the device verification stage and a rugged, but not damaging, insertion mechanism for production tests. Often the test systems and fixtures need to interface to environmental chambers. In addition to the test system, burn-on systems for multiple units are required.
