This work presents the study and development of a bidirectional DC-DC converter applied as a semiconductor test platform, whose objective is to analyze the conduction and switching losses in those devices under test. The platform has comprehensive specifications to enable testing of various types of semiconductors, it can receive two types of packages, in addition to accepting connections with modules, the converter can operate in two modes, in Buck mode, step-down, or in Boost mode, step-up, with the duty cycle fixed in 0:5, the converter operating voltage range is from 12 V to 400 V and the current range is from 0 A to 20 A. Its nominal power can reach up to 2 kW. The converter operates in closed loop with the average current method control, has three loops, but will only works with two simultaneously. To validate this design carried out the converter was simulated for all operating conditions. The simulation results obtained are presented, as well as the tests performed in the semiconductors, the results of the laboratory-built prototype are also presented.
