摘要
传统Buck-Boost变换电路只能进行DC/DC变换,不能输出交流正弦电压,本文针对组合式Buck-Boost逆变器主电路拓扑,提出了一种新颖的控制方法,该方法能够有效控制主电路输出正弦脉宽调制的电压波形。最后,基于组合式Buck-Boost逆变器主电路,进行了该控制方法的MATLAB/SIMULINK仿真,并以DSPIC30F单片机为控制核心,搭建了实验平台,仿真和实验结果验证了该控制方法的有效性和可行性。
The tradition buck-boost converter can only transform DC to DC, can not output AC sine voltage. This paper proposes a new control method for the main circuit topology of combined Buck-Boost inverters. This method can effectively control the main circuit to output sine pulse width modify(SPWM) voltage waveform. Finally, the main circuit simulation model of the combined Buck-Boost inverter is built on MATLAB/SIMULINK, and experiment platform is set up by using DSPIC30F series singlechip as the control center to verify the control method. The feasibility and validity of the method are confirmed by simulation and experimental results.
