| 摘 要： | 三相AC/DC整流器作为许多电力电子设备中不可或缺的电气环节得到了广泛的应用。相比于传统的二极管整流器及相控整流器,VIENNA整流器具有网侧谐波含量低、功率因数高的优点。同时,VIENNA整流器比普通桥式PWM整流器具有更少的功率开关数量,进一步提高了系统功率密度。在简要介绍VIENNA整流器原理的基础上,结合3 k W系统进行了相应的工程设计,主要包括储能元件设计、滤波环节设计和控制环路设计。此外,针对电网电压畸变带来的输入电流谐波问题,采用了一种结合VIENNA整流器控制环路的指定次谐波优化方法,并针对其中LCL滤波器带来的谐振问题,从工程设计的角度进行了相应的优化。3 k W工程样机的实验结果进一步验证了设计方法以及所采用的优化方法的有效性。

| Abstract: | As an essential electrical section in many power electronics devices, three-phase AC/DC rectifier has been widely applied. Compared with the traditional diode rectifier and phase controlled rectifier, a VIENNA rectifier features low total harmonic distortion(THD) and high power factor. Meanwhile, its system power density is much higher than that of the traditional bridge pulse width modulation(PWM) rectifier because of its fewer power switches. Based on a brief introduction of the principle of VIENNA rectifier and with the combination of a 3 kW VIENNA system, the corresponding engineering design is carried out in this paper, including the design of energy storage elements, filter section and system control loop. In addition, to solve the input current harmonics problem caused by the distortion of grid voltage, an optimizing method for the harmonic currents of selective orders is applied with the combination of the control loop of VIENNA rectifier; moreover, the resonance problem due to LCL filter is optimized from the perspective of engineering design. The experimental result of a 3 kW VIENNA prototype further verified the effectiveness of the design method and the corresponding optimization method. |
