ABSTRACT

Abstract:

The presented work shows further improvement made to the current sensorless control of a boost-type switch-mode rectifier using an adaptive inductor model. Modern industry offers various analog controllers for power factor correction purposes. Their manufacturers claim to provide the capability to control a broad range of input and output parameters. The existing rectifier has several major advantages over conventional power factor correction (PFC) converters. It is controlled by fully programmable digital signal processor, it does not utilize a current sensing resistor for current feedback, it is capable of calculating real values of rectifying inductor parameters employed for current values calculation etc. However, the developed converter had one significant drawback - limited input voltage range. The focus of the presented project is an extension of alternating voltage range that can be supplied to the described circuit.
