摘要
针对有源箝位谐振直流环节逆变器提出了一种新的双幅控制策略。通过直流环节采用母线电压双幅控制和逆变桥采用带有三态滞环电流调节器的电压电流双闭环控制相结合的策略,可以降低直流环节的损耗,改善逆变器的输出特性。它具有控制简单,输出电流脉动小,输出电压谐波含量小等优点。详细分析了电路的工作原理和控制策略,并给出了仿真和实验结果。
A novel two-amplitude control strategy for active-clamped resonant DC link inverter is proposed. By the scheme of the two-amplitude control strategy in conjunction with the dual-loop control strategy which has a three-mode hysteresis controlled current regulator, it can decrease the DC link losses and improve the output performance. It has the advantages of simple controller, low current ripple, low output voltage harmonics and so on. The operating principle and control scheme are analyzed in detail, and verified by the simulation and experiment results.
