Addressing DC Power Test Challenges for Base Station Subassemblies
应用文章
Electronic subassemblies for base stations derive individual circuit voltages from a main DC bus voltage through a series of DC/DC regulators. Due to the complexity of their distributed power architecture, base station providers are faced with a number of challenges during development and production test of subassemblies.
Challenges include:
- Assuring operation under a speciied sequence of many bias voltages and tolerance to change in timing and sequence.
- Validating peak and steady state power demands under worst case operating conditions for power budgeting purposes
- Make certain turn-on inrush current is within acceptable limits
- Measure current demand and verify tolerance under abnormal voltage conditions
