摘要

分析了一种用于高功率因数和恒定输出电压的前端(FE)功率转换的单相h桥晶体管变换器。根据变换器升压模式工作的要求，从基本电路方程推导出平均状态空间模型。利用状态空间模型得到了变流器的运行平衡点。由于变换器被用作逆变器的电压源，因此在其输出处保持恒定的直流电压的要求成为必要的标准。设计了两种闭环输出电压的反馈控制方案。通过仿真研究比较了它们的性能。对该变换器开环工作进行了一些实验研究，并在升压工作模式下取得了结果。

Control of a transistorised single-phase bridge converter operated in the rectifier mode

A single-phase H-bridge transistorised converter intended for front-end (FE) power conversion at a high power-factor and a constant desired output voltage has been analysed. Based on the desired boost-mode operation of the converter, the average state-space model has been derived from the basic circuit equations. Equilibrium points of operation of the converter have been obtained from the state-space model. As the converter is intended for use as a voltage source for an inverter, the requirement of maintaining a constant DC voltage at its output becomes a necessary criterion. Two feedback schemes for controlling the output voltage in closed-loop have been designed. Their performances have been compared by simulation studies. Some experimental studies on the converter operating in open-loop have been made and results obtained in the boost-mode of operation.
