| Abstract |
The performance of the TPS dipole power supply for the dipole magnets in the TPS storage ring is important. As the output current of the power supply follows the beam current for operation at 3 GeV, the power supply must deliver enormous energy to the dipole magnets. The target energy corresponds to 700 A at 800 V. The dipole supply for the TPS storage ring is a unipolar switching power supply, also called a bulk power supply. The TPS dipole power supply modulates the output current regulated by the PWM signal. The switching device is an IGBT module working at frequency 2 kHz. A PID controller and a DCCT are used for feedback control of the output current. We obtained an optimal control gain with long-term stability of the output current under 10 ppm. The performance of the TPS storage ring dipole supply can thus satisfy the TPS requirement. The beam current generates 3 GeV in the TPS ring. This paper reports the excellent results.
