摘要:
针对图腾柱无桥PFC在CCM工作模式下高频管温升高和电压过零点畸变问题,提出了一种半周期高频半周期工频的数字控制策略。将功率开关管替代传统图腾柱拓扑中的二极管,分析了改进后拓扑的原理和模态,构建了拓扑电路的小信号模型,应用基于无差拍控制原理的电压前馈双闭环控制,搭建了一台400 W的AC/DC实验样机验证该控制策略的有效性。结果表明,当输入176~264 V交流,输出400 V直流时,整机峰值效率97.9%,满载自然冷却下最高温度点80 ℃,输入电流THD达到2.9%。在满足高效率下该控制策略较传统控制策略能够更好实现器件温度均衡和输入电流正弦度。
Abstract:
This paper proposes a half-cycle high-frequency and half-cycle power frequency digital control strategy to address the temperature rise and voltage zero-crossing distortion of the high-frequency tube in CCM operating mode of Totem Pole non-bridge PFC. The study involves replacing the diode in the traditional totem pole topology by a power switch tube; analyzing the principle and mode of the improved topology; constructing the small signal model of the topology circuit; and developing a 400 W AC/DC prototype by applying a voltage feedforward double closed loop control based on deadbeat control principle to verify the effectiveness of the control strategy. The results show that 176-264 V AC input and 400 V DC output results in the peak efficiency of 97.9%, the highest temperature point of 80 ℃ under full load natural cooling, and the input current THD of 2.9%. Under high efficiency, this control strategy enables a better device temperature balance and input current sinusoidality than the traditional control strategy.
