A Novel FPGA-Based Digital Power Controller Architecture

In this paper, we design a novel controller based on modular bus software and hardware architecture. The proposed controller uses the FPGA as the hardware carrier, and integrates the external expansion type Avalon bus with the discrete IP module structure to realize the all-digital, efficient and reliable fast closed-loop regulation power control. Based on the requirements of the original related functions, the digital controller greatly reduces the FPGA resource consumption and improves the efficiency of hardware resources. Meanwhile, it provides a powerful experimental data reference for the modular design of the digital power controller. Moreover, the designed controller is successfully applied on Cooler Storage Ring of the Heavy Ion Research Facility in Lanzhou (HIRFL-CSR) six-pole magnet power supply.
