摘要：

The output characteristics of Boost Zero-Voltage Switching Quasi-Resonant Converters, presented in previously published works, are calculated considering equal input and output energies. Nevertheless, measurements that were taken with different breadboarded Boost ZVS-QRCs demonstrate an important deviation between the results of the theoretical analysis and the experimental ones. The deviation becomes greater when the load current increases. This paper deals with a novel simulation method to approximate the real behavioural characteristics of Boost ZVS-QRCs. Analytical expressions are derived to calculate the power losses at each converter component as well as the d.c.-voltage conversion ratio. The computer simulation results are confronted to experimental ones proving the effectiveness of the proposed method.
