摘要
本文提出了一种利用DELTA变换技术对中频逆变电源进行补偿以获得高品质正弦波的新方法。根据DELTA逆变技术的原理,研究了DELTA逆变器的控制方法,并建立了基于此控制方法的正弦波整形控制的仿真模型,用MATLAB中的仿真工具箱SIMULINK对控制技术进行了仿真。仿真结果表明,DELTA补偿技术能有效的改善逆变器输出波形,大大降低正弦波的电压波形畸变率,减少了电源的谐波含量。
A novel way is given in the paper,which is used to improve the factors of medium-frequency Sine- wave-supply with DELTA inverters.According to the principles of the DELTA technology,this paper discusses the way of controlling the DELTA inverter,and a simulation model based on the MATLAB is established for testifying.The simulation result demonstrates that DELTA compensating technology can improve the quality of the output waveforms and reduce the THD of voltage sine-waves.
