为了改善二极管整流器的电流波形，提出了一种新的倍压二极管整流器工作原理。在传统的倍压整流电路中，使用较大的电容器来提高输出电压，而本文提出的电路使用较小的电容器和小型电抗器来提高输出电压，但改善输入电流波形。给出了一种电路设计方法，并进行了实验验证。1.6kW整流器的实验结果表明，所提出的二极管整流器满足谐波导线要求。输入功率因数高达97%，效率高达98%。新的整流器不需要控制开关来满足谐波导线，与升压型电流改善电路相比，产生了简单，可靠和低成本的ac- dc转换器。
To improve the current waveform of diode rectifiers, we propose a new operating principle for the voltage-doubler diode rectifiers. In the conventional voltage-doubler rectifier circuit, relatively large capacitors are used to boost the output voltage, while the proposed circuit uses smaller ones and a small reactor not to boost the output voltage but improve the input current waveform. A circuit design method is shown and confirmed experimentaly. The experimental results of a 1.6kW rectifier show that the proposed diode rectifier satisfies the harmonic guide lines. A high input power factor of 97% and an efficiency of 98% are also obtained. The new rectifier needs no controlled switches to meet the harmonic guide lines, resulting in a simple, reliable and low-cost ac-to-dc converters in comparison with the boost-type current-improving circuits.
