Abstract

A digital controller for satellite medium power DC/DC converters is presented. The power converter composes of a digital compensator implemented in the FPGA, peripherals that interference the digital part with the analog ones and a power stage. The presented controller can be used in two topologies: buck and half-bridge. The mathematical models of the power stages, quantizers and the controller are given. Practical verification is done based on 1kW buck and 350W half-bridge converters. The theoretical results were in good agreement with the measured Bode plots.
