| 摘 要： | 提出了一种基于双幅有源箝位谐振直流环节逆变技术的脉宽调制(PWM)控制方案,以改变传统谐振直流环节逆变器只能采用离散脉冲调制(DPM)控制的现状,在保持原电路结构简单,软开关等优点的基础上,使逆变器具有更高的效率,明显改善了输出频谱.给出了PWM控制方案的工作原理,通过3kW实验系统的仿真和实验,证明了该控制方案的可行性和优越性.

| Abstract: | The traditional resonant DC-Link inverter can only use Discrete Pulse Modulation(DPM) control.Based on two amplitude actively clamped resonant DC-Link technique,the Pulse Width Modulation(PWM) control strategy is proposed,which keeps the traditional advantages,such as simplicity,soft-switching condition and improves the frequency performance.The working principle of PWM control is given,and PWM control with instantaneous current feedback is used in control circuit.Simulative and experimental results of the 3kW system verify its feasibility and advantage. |
