Description

Technical field [0001] The present invention relates to the field of power controller, and more particularly to a reconstructed architecture and implementation method based on an integrated circuit. Background technique [0002] Excellent integrated circuit input and output ports such as Field Programmable Gate Array (FPGA), Digital Signal Processor, DSPs are enriched, and the control mode is advanced, which can meet the system multiplexed independent input, multiple ways. PWM independent output, etc., which is advantageous for integration and performance optimization of space power. At the same time, the ultra-large-scale integrated circuit such as FPGA is susceptible to various radiation in the universe. If the probability of single particle effect is greatly improved, the higher the integration of the device, the more significant constraints of single particle effects, which seriously restricts digital power supply Application in space. [0003] Therefore, it is important to d...
