In this article, a new two-switch, single-phase, power-factor-correction, discontinuous-conduction-mode boost rectifier that features zero-voltage switching turn on and can achieve less than 5% input-current total harmonic distortion (THD) by injecting a simple feedforward signal obtained from input and output voltages to the output voltage feedback control is introduced. Since low THD is achieved without high- bandwidth active current shaping control, the proposed topology is suitable for modern aviation applications that require line frequency up to 800 Hz. The evaluation was performed on a 320-W prototype designed to operate from 94–134-V line input and deliver 220-V dc output. The prototype achieves 3.3% THD at full load over the line frequency range from 360 to 800 Hz and meets the required harmonic limits specified by the DO-160 standard that describes the environmental conditions and test procedures for airborne equipment.

用于航空应用的低 THD 两开关 PFC DCM 升压整流器

在本文中，一种新型双开关、单相、功率因数校正、断续传导模式升压整流器具有零电压开关开启功能，可实现低于 5% 的输入电流总谐波失真 (THD ) 通过将从输入和输出电压获得的简单前馈信号注入到输出电压反馈控制中。由于无需高带宽有源电流整形控制即可实现低 THD，因此所提出的拓扑适用于需要高达 800 Hz 线路频率的现代航空应用。评估是在 320-W 原型上进行的，该原型设计用于在 94-134-V 线路输入下运行并提供 220-V 直流输出。原型达到3。
