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
