基于DSP和PIC的多级H桥变换器的控制器设计

Design of DSP and PIC-based Control System for Multi-level H-bridge Converter

在简要介绍一种18脉波多级H桥电压型变换器的基础上,详细论述了该变换器基于DSP和PIC的控制器的软硬件设计,软件设计采用状态输出法。该控制器已成功应用于多级H桥变换器的试验系统。最后,给出了系统的实验波形。

This paper describes an 18-pulse multi-level H-bridge voltage-source converter briefly and discusses the design of DSP and PIC-based control system for the converter in detail,including the design of the software with state-output and the hardware.This kind of control system has been successfully used in the experimental system.The experimental waveforms are also given.
