  The Taiwan Photon Source (TPS) is a latest generation synchrotron light source. Stringent power supply specifications should be met to achieve design goals of the TPS. High precision power supply equipped with 20, 18, and 16 bits DAC for the storage ring dipole, quadrupole, and sextupole are equipped with Ethernet interfaces. Control interface include basic functionality and some advanced features which are useful for performance monitoring and post-mortem diagnostics. Power supply of these categories can be accessed by EPICS IOCs. The corrector power supplies' control interface is a specially designed embedded interface module which will be mounted on the corrector power supply cages to achieve required performance. The setting reference of the corrector power supply is generated by 20 bits DAC and readback is done by 24 bits ADC. The interface module has embedded EPICS IOC for slow control. Fast setting ports are also supported by the internal FPGA for orbit feedback supports.
