AI Technical Summary
Traditional high-voltage power supply control systems and methods cannot meet the requirements of high power output voltage (output voltage up to 120kV), voltage power up to 10MW, low ripple, fast dynamic response, and shutdown-restart function.
A high-voltage power supply control system based on PXI technology is adopted. Three FPGA boards are used for module drive signals and status monitoring. The collaborative control of 168 controlled power modules is achieved through master-slave control method. P2P protocol and DMA FIFO method are used to reduce data transmission latency. The embedded processor only updates the parameters of the master control card.
It achieves the requirements of flexible operation mode, reliable control, high output voltage level, voltage power up to 10MW level, low ripple and fast dynamic response of high voltage power supply, reduces CPU utilization and data transmission latency, and improves system integration and output accuracy.
