This paper proposes an approach to estimate the parameters of an AC-DC boost power factor corrector converter which includes an EMI filter. To this end, once the topology is known, measurements at the input and output terminals of the converter are done to identify the values of the passive elements. The proposed methodology is based on the trust-region nonlinear least squares algorithm to identify the parameters of the converter. The steady-state and the transient signals of the converter at the input/output terminals are acquired non-intrusively without any internal modification of the circuitry. The accuracy of the parameter identification carried out is determined by comparing the estimated values with the actual values provided by the manufacturer, and by contrasting the measured signals with the ones obtained with a simulation model with the estimated values of the parameters. The results presented in this paper prove the accuracy of the proposed approach, which can be extended to other power converters and filters.

This paper designs a novel single phase high power factor rectifier with IR1150 as its main control chip, which main circuit uses boost topology. The fundamental principle of the proposed rectifier is introduced. The IR1150 control IC based on one cycle control is intended for boost converters for power factor correction operating at a fixed frequency in continuous conduction mode (CCM). The use of the IC will make the PFC circuit design easily, the volume of the rectifier small and the efficiency enhancing. The modules of the proposed rectifier such as current loop and over-current protection, voltage loop and over-voltage protection, soft start, and so on, are analyzed and designed respectively in detail. Experimental results of the designed 600W prototype prove that the boost high power factor rectifier designed is rational and reliable, its power factor can reach 0.994.
