摘要
提出了占空比扩展高频脉冲直流环节逆变器新思路 ,深入分析研究了该软开关逆变器工作原理、三态离散脉冲电流滞环跟踪控制策略 ,获得了关键电路参数设计准则。设计并研制成功的 75 0VA 2 7VDC/115V4 0 0HzAC逆变电源具有体积重量小、变换效率高、静态精度高、动态响应速度快、输出波形失真低、过载与短路能力强、可靠性高等优良的综合性能。
A novel idea of inverter with duty cycle extended high frequency pulse dc link is proposed. The operation principle of the soft switching inverter and the control strategy of three state discrete pulse modulation hystersis current are deeply analyzed and studied. The design criterions of key circuit parameter are gained. A designed and developed 750VA 27V DC/115V 400Hz AC prototype has excellent comprehensive advantages.
