中頻逆變器波形控制策略仿真研究

摘要：本文研究了400Hz恒壓恒頻(CVCF)中頻逆變器的波形控制策略，建立了單相逆變器的數學模型，詳細分析了準諧振控制器對逆變器的影響，提出了一種基于準諧振控制器的多閉環波形控制策略。通過Simulink仿真，驗證了波形控制策略的可行性。 敘詞：中頻逆變器 準諧振控制器 多閉環控制 Simulink仿真 Abstract：The waveform control scheme of 400Hz-CVCF inverter is discussed in this paper.The math mode of single phase inverteris established,the effect of resonant controller is concerned.A multi-loop control scheme based on resonant controller is put forward.The results of Simulink valid the feasibility of control scheme.
