基于ZYNQ-7000的悬浮型脉冲电源控制器设计OA

Conventional floating-type pulse power controllers,typically built on DSPs,FPGAs,or MCUs,often suffer from limitations such as poor flexibility,low processing speed,and limited scalability.A novel floating-type pulse power supply controller based on the ZYNQ platform is designed.An ARM-FPGA cooperative architecture is adopted,which ensures high control accuracy while flexibly adapting to various control scenarios.In the design,the PL side is responsible for functions such as ADC sampling,PWM calculation and output,while the PS side handles TCP/IP communication,protocol parsing and PI computation.Data interaction is achieved via the AXI-Lite bus,enabling both open-loop and closed-loop control.The testing of logic analyzer(ILA)and prototype pratical testing under both open-loop and closed-loop conditions is conducted.The experimental results demonstrate that under a 790 V bus voltage and 1 900 A target current,the control strategy can realize a bandwidth of 1.6 kHz and a tracking error within±0.2 A,meeting practical power supply requirements while offering excellent scalability and flexibility.
