Today, the FPGA (Field-Programmable Gate Array), due to their paralleled architecture, configurability, large amount of logic resources, full-custom digital-signal processing (DSP) units, and storage elements, has taken a very important role in the HIL simulation and rapid prototyping of electrical industrial applications. In fault-tolerant applications, to have a fast fault detection, a small simulation time step is required for the real-time simulator. Such real-time simulation can validate the new proposed algorithm under extreme conditions in a non-destructive environment. The HIL simulation is an intermediate step before applying controllers, fault detection methods, and protective devices in a real system. However, real-time digital HIL simulation, which has to interact with external devices, can be a reliable and cost-effective virtual scenario for rapid prototyping of electrical systems. Although the execution time of such offline simulators is optimized, it is not always satisfactory for some critical applications. In some applications, such as fault detection and fault-tolerant systems, a very fast simulator is required. Offline simulation of electrical and electronic applications by software such as MATLAB/Simulink and other simulation tools has greatly progressed in recent years. Thanks to the FPGA implementation and algorithm performances, the fault can be detected in less than one switching period. Both simulations and HIL results confirm the validity and effectiveness of the proposed UFD. ![]() In Section 5, the principle of an experiment based on Hardware-in-the-Loop (HIL) is first explained and then applied to the case of a two-stage buck/buck–boost converter with fault-tolerant capability, based on synchronous control and a redundant switch. Selected simulation results are presented and discussed in Section 4. ![]() ![]() Finally, both of them are compared at the end of the section. Then, two-fault detection approaches are detailed in the case of the two-stage DC-DC converter, based on parallel Fault Detection (FD) and on the proposed Unified Switch Fault Diagnosis (UFD). In Section 3, the general principle of switch fault detection in two-stage converters is first introduced. In the following section, the classical DC-DC converters are discussed.
