AB  - Sirius is a 4th generation synchrotron light source de-signed and being built by Brazilian Synchrotron Light Laboratory (LNLS), with first beam scheduled for 2019. Approximately thousand power supplies (PS) will be needed to feed all the magnets, being 57 to operate the booster injector. The two booster dipole PS are the most complex, not only due to their higher current (1.1 kA), voltage (800 V) and power (333 kW) output, but also because the current must follow a quasi-triangular waveform, from a value close to zero to almost the maximum in 320 ms and at a repetition rate of 2 Hz. Due to the high output values, each PS is formed by two sets in parallel of 4 modules in series, what means 8 modules with 550 A / 200 V output. In order to reduce the 2-Hz effect in the grid, each module has two main stages. The input stage has the function to regulate the average voltage in a capacitor bank consuming a constant RMS current from the grid, which value depends on of the PS average output power. The output stage has the function to transfer the energy from the capacitor bank to the load, with the output cur-rent following the reference waveform. This work describes this PS, showing its topology, some aspects of its design and obtained results.
