摘　　要：本文分析研究了一种电流滞环控制逆变器的工作原理,其采用三态电流滞环控制,以输出电压误差放大信号作为输出滤波电感电流的给定信号,使得输出滤波电感电流在一定范围内滞环跟踪变化。给出了滞环宽度和输出滤波电感等关键电路参数的选取与设计方法;设计并研制了一台原理样机。仿真分析及实验结果表明,电流滞环控制逆变器具有控制简单、可靠性高、动态响应速度快、抗短路能力强、变换效率高等优点。The operation principle of DC/AC inverter with hysteresis current control was analyzed and studied. The inverter is controlled with three-state hysteresis current which follows the error signal of output voltage. Selections for key circuit parameters were given, and a prototype was designed and manufactured. Simulation and experimental results show that DC/AC inverter with hysteresis current control has advantages of simple control, high reliability, fast dynamic response, strong ability of anti-short-circuit and high efficiency.
