EA 10000 Series Power Supplies and Electronic Loads Transition to Digital Share Bus for Enhanced Parallel Operation
Parallel power systems rely on effective communication between instruments to ensure accurate current sharing and stable operation. The Share Bus on the EA 10000 Series is moving from pulse-width modulation (PWM) to pulse-code modulation (PCM) to enable enhanced system performance, and all instruments within a system must be using the same modulation.
This technical brief:
- Explains the limitations of PWM-based share bus signaling in parallel systems.
- Describes how PCM-based communication improves dynamic response and system stability.
- Details improvements in resolution for more precise current balancing.
- Highlights deterministic timing benefits for predictable control loop performance.
- Outlines firmware compatibility requirements and firmware update procedures.
