Research On Passive-based Control Of Passived Integration Boost ZCS-QRCs

This article first establish Boost zero current quasi resonant converter(ZCS-QRCs) mathematical model and simplifies the model by appling the time average method . Then, introduce modeling method of the passived integration and put forward a new kind of passive integration structure and lay the foundation for model building of resonant unit of Boost ZCS-QRCs passived integration .Moreover, describes the principle of common modeling method and controlling means for Boost ZCS-QRCs, and focus on study the nonlinear control method of this converter, then the concept of passive control is introduced. And then, starting from derivated the rules of Boost ZCS-QRCs passive control . First the derivation of passive control methods and simulation verification are given in Simulink of MATLAB7.1. It is shown that passive control can be applied to the Boost ZCS-QRCs, and improve its steady-state and dynamic performance. Finally, the passive control is introduced into planar passived integration, and this article attempt to combine the advantages of passived integrate and passive control to further improve the performance of Boost ZCS-QRCs. The simulation results of the Boost ZCS-QRCs based on passive control are provided Compared to traditional Boost ZCS-QRCs. It confirms that the steady-state ripple and dynamic response have been improved by the passived integration Boost ZCS-QRCs based on passive-based control.
