AI Technical Summary
Technical Problem
The output current of the power amplifier contains switching ripple components, which affects the control accuracy, especially in the magnetic levitation bearing control system, leading to increased electromagnetic force fluctuations and circuit losses in the magnetic levitation bearing.
Method used
The optimal phase shift angle is determined within a set phase shift angle range using a simulated annealing algorithm. The output current of the power amplifier is phase-shifted and superimposed through a phase shifting circuit to reduce current ripple.
Benefits of technology
This reduces the switching ripple component of the power amplifier output current, improves the accuracy and stability of the control system, and reduces circuit losses.
