Research on an innovative topology of PFC based on a space nuclear power system

Abstract

AC/DC power converters have been widely implemented in a variety of power systems. Power factor correction (PFC) is considered as one of the significant technologies in AC/DC converters, which has been researched deeply. A new topology of the boost PFC converter is investigated and related operating principles are analysed. The state space modelling approach is applied to evaluate the performance of the boost converter based on the continuous current mode. To demonstrate the stability of the overall system, an optimal design of a compensation network is carried out through the analysis and modelling of the boost PFC converter. The parameters of the proportional integral controller are determined through the theoretical design and mathematical derivation of the voltage loop and current loop. The control strategy and transient response of the converter are verified in MATLAB SIMULINK, which is able to achieve the zero-phase and sinusoidal tracking between input current and input voltage.
