Abstract :
The use of silicon rectifiers in the continuous mode boost converter results in excessive reverse recovery currents. In order to overcome this problem, one solution is to use soft-switching techniques, such as the ZVT technology, while another solution is to use better rectifiers, namely, GaAs rectifiers. In this paper, two PFC boost converters are built to compare the benefits derived from these two solutions and to compare the performances of silicon rectifiers and the GaAs rectifier
