摘要

直流链路串联谐振(DCLSR)是功率转换中的一个新概念，特别是使用IGBT进行直流到交流转换。本文研究了并联逆变器在共/分布式负载下的运行和控制策略。输出电压和负载对链路电流的直流耦合控制使并联逆变器能够以输出电压正弦的方式共享与其单个逆变器容量成正比的负载功率。通过仿真验证了逆变器的运行和上述控制策略及其数字化实现。结果验证了并联逆变器在所有负载和瞬态(包括短路)条件下的可靠运行和负荷分担。介绍了该逆变器的实用性和可靠性。

Operation, control and performance evaluation of parallel connected DC link series resonant inverter delivering to distributed load

DC link series resonance (DCLSR) is a new concept in power conversion and in specific to DC to AC conversion using IGBT. In this work, the operation and control strategies of parallel connected inverters delivering to common/distributed load are investigated. The DC-coupled control of link current from output voltage and load enables the parallel connected inverters to share the load power proportional to its individual inverter capacity with output voltage sinusoidal. The inverter operation and above control strategy and its digital implementation are verified through simulation. The results verify the reliable operation and load sharing of inverters connected in parallel at all loads and transients including short circuit condition. The practical and reliability aspects of this inverter is presented.
