Abstract :
This paper analyzes the error of digital control PFC system in the presence of digital signal processing, the control loop of PI, PID controller is equivalent to IIR digital filter, the mathematical statistics of errors by the control loop is calculated and the transfer model of noise in the system is gave. these works for the digital control PFC system to choose the right processor and reduce the impact of errors provides a strong reference.
