基于软开关技术的高频链并联逆变器的设计
High-frequency link parallel inverter based on soft-switch technology
摘要
Abstract
Soft-switching technology and parallel control technique is considered an important development direction of today's inverter.This paper studies soft-switching technology,digital control technology and non-connected in parallel,developes high-frequency link inverter power source based on DSP.The inverter adopts full-wave full-bridge type topology.The main circuit is composed by the fullbridge inverter, high-frequency transformer,frequency converter and the input and output filter components. The full-bridge inverter achieves the zero-voltage zero-current soft-switching. The controller uses the modified PQ technology based on the current disintegration. So the inverter overcomes the limitation of bad current sharing in nonlinear load.The results of MATLAB and PAPICE simulation on the system show the system design has achieved an ideal parallel operation results and the waveform of simulation prove the parallel inverter has good performance.关键词
