Equipment Compatibility Study of High Voltage Power Supplies for Radiation Sterilization
As the core energy supply unit in radiation sterilization systems, the equipment compatibility of high-voltage power supplies directly affects flexible production line upgrades and multi-scenario applications. This paper analyzes compatibility mechanisms and technical pathways from three dimensions: interface protocol standardization, dynamic parameter matching, and multi-system coordination.
1. Standardized Design for Multi-Device Interfaces
1. Physical Interface Compatibility
Modern radiation equipment includes heterogeneous systems like electron linear accelerators and beam scanning devices, requiring power supplies to support 10kV-5MV wide-range voltage output and comply with BNC/SHV connector standards. Modular interface design reduces device switching time to 15 minutes, achieving 83% higher efficiency than traditional solutions.
2. Unified Communication Protocols
CAN bus architecture based on IEC 62557 enables millisecond-level data exchange between power supplies and PLC systems. In a pharmaceutical production case, Modbus-TCP integration reduced parameter synchronization errors from ±2.1% to ±0.3%.
2. Dynamic Parameter Matching Technology
1. Load Adaptive Adjustment
The voltage-beam intensity coupling model:
\( V_{out} = k \cdot \sqrt{I_b \cdot Z_0} + V_{offset} \)
maintains ±0.05% voltage stability across 0.5-20mA beam currents.
2. Energy Spectrum Dynamic Compensation
Segmented voltage control algorithms achieve 4.5% FWHM during 300kV-2MV switching, eliminating sterilization blind zones.
3. Multi-System Collaborative Control
1. Thermal Management Coordination
Temperature-power joint control modules limit efficiency decay to 3% in 25-40℃ environments, enabling 72+ hours of continuous operation.
2. EMC Optimization
Three-stage shielding reduces 30MHz-1GHz radiation to <10dBμV/m, lowering interference with spectrometers by 98%.
4. Compatibility Verification System
1. 3D Field Distribution Testing
64-channel probe arrays detect ±1% local field distortion, ensuring beam uniformity.
2. Accelerated Life Testing
Arrhenius-model aging tests confirm MTBF reaches 50,000 hours with <0.01%/kHr component decay.
Future digital twin integration will enable real-time virtual-physical mapping, advancing radiation sterilization equipment toward intelligent and flexible evolution.
