Application of Digital Control Technology and Intelligent Parameter Configuration in Adjustable DC High-Voltage Power Supplies

Adjustable DC high-voltage power supplies are used in electrostatic testing, capacitor charging, and precision instrumentation. Digital control technology enables these systems to achieve unprecedented levels of accuracy, repeatability, and configurability.
By employing high-resolution ADCs and fast DSP or FPGA controllers, modern systems implement dual-loop regulation—an inner current loop for rapid protection and an outer voltage loop for precision control. Digital PID, adaptive, or sliding-mode controllers ensure stable operation even under load disturbances.
Intelligent parameter configuration through software interfaces allows automatic tuning of voltage ramps, current limits, and protection thresholds. Advanced algorithms perform self-learning and real-time adjustment based on historical operation data, optimizing performance across different load conditions.
Communication through RS485, CAN, or Ethernet enables remote monitoring, logging, and control. Combined with data acquisition and diagnostic features, digital control transforms traditional HV supplies into intelligent, user-adaptive systems suitable for research and industrial automation.
