Abstract :
A new fault diagnostic method is presented in this paper for bidirectional half-bridge DC-DC converters. This algorithm uses only the converter control variables without requiring extra-sensors and its implementation requires only a minimum computational effort. Simulation results in a wind power system including supercapacitors and batteries have been used to validate the fault diagnostic method under different operating conditions.
