Abstract This paper presents an extensive simulation-based and experimental validation of One-Cycle Control (OCC) over a nine-level power inverter using Cyclone III FPGA from Intel. OCC is a technique that exploits the nonlinear nature of multilevel power converters to overcome issues such as fast dynamic response, robustness and perturbations on either the source or the load side. Simulations performed in Modelsim demonstrate the elimination of dynamic and steady-state error between the switched output and reference signals on application of OCC. Simulink-based development and testing of the multilevel inverter model is also carried out under varying load conditions to record the reference signal, current, power factor and total harmonic distortion. The applied control scheme exhibits negligible current distortion and instability concerns when the converter is lightly loaded. Altera Quarturs II is further used for the VHDL-based implementation and experimental testing of the developed algorithm thus, validating the robustness of the control strategy.

基于FPGA的单周期控制九电平逆变器仿真与实验验证

摘要 本文介绍了使用英特尔 Cyclone III FPGA 对九电平功率逆变器的单周期控制 (OCC) 进行广泛的基于仿真和实验验证。OCC 是一种利用多电平电源转换器的非线性特性来克服快速动态响应、鲁棒性和源端或负载端扰动等问题的技术。在 Modelsim 中执行的仿真证明了在应用 OCC 时消除了开关输出和参考信号之间的动态和稳态误差。基于 Simulink 的多电平逆变器模型的开发和测试也在变化的负载条件下进行，以记录参考信号、电流、功率因数和总谐波失真。当转换器轻载时，所应用的控制方案表现出可忽略不计的电流失真和不稳定性问题。Altera Quarturs II 进一步用于开发算法的基于 VHDL 的实现和实验测试，从而验证控制策略的稳健性。
