An Original Method to Simulate Diodes Rectifiers Behaviour with Matlab-Simulink Taking into Account Overlap Phenomenon

This paper presents a simple and original method in order to simulate the behaviour of AC to DC converters with Matlab-Simulink. This approach takes into account overlap phenomenon, continuous and discontinuous conduction mode. The AC to DC converter is presented as a block (voltage input and voltage output) which can be inserted in a complex structure. The simplicity and the low computing-time of this method makes it an interesting alternative to the Matlab´s Power-Systems toolbox and hybrid simulation with PSIM and Matlab. Simulations results are presented and compared to experimental results.
