Abstract

Regulation of the load voltage of inverter for intermittencies in source and load is a tedious task. For this purpose, various techniques have been discussed in the state of the art. Among the various methods, the PI controller is widely used. However, the major limitation of this method is complex computations involved in obtaining the values of proportional and integral gains. In this regard, this paper focuses on hysteresis voltage control for inverters in which no complex computations are involved. The major advantage of the hysteresis control is that the load voltage always follows the reference waveform irrespective of the intermittencies. The implementation of the controller for basic inverter topologies has been investigated. Further, the possibility of implementing the hysteresis voltage control for multilevel inverters has been investigated. This method has been applied for a basic half-bridge and full-bridge inverters in the MATLAB/Simulink environment. Further, it has also been validated for the T -type multilevel inverter for various intermittencies.

不同逆变器拓扑的迟滞电压控制实现

电源与负载间歇时逆变器负载电压的调节是一项繁琐的工作。为此目的，在目前的技术状态中讨论了各种技术。在各种控制方法中，PI控制器的应用最为广泛。然而，该方法的主要限制是在获得比例增益和积分增益值时涉及复杂的计算。在这方面，本文主要研究逆变器的磁滞电压控制，不涉及复杂的计算。迟滞控制的主要优点是负载电压始终遵循参考波形，而不考虑间歇。研究了基本逆变器拓扑控制器的实现。此外，还研究了在多电平逆变器中实现迟滞电压控制的可能性。该方法已在MATLAB/Simulink环境下应用于一个基本的半桥和全桥逆变器。此外，还对T型多电平逆变器进行了各种间歇的验证。
