| Abstract |
In TPS (Taiwan Photon Source) project, 58 home-built small form factor bipolar power supplies are used to fine-tune the trim coil of booster ring bending dipole magnets. With the preliminary analog PI control loop design version, current output will tend to behave with poor linearity around zero current. By employing DSP chip, a full digital PI control loop design together with optimal MOSFT switching algorithm and 13bits PWM output capability is capable of improving the output current performance around zero current. Before the final realization, MATLAB SIMULINK is utilized to find out the optimal MOSFT switching algorithm, and then physical circuit is implemented and tested. The result and design will be demonstrated in this paper to show significant improvement around zero current.
