高频软开关静止变流器并联研究

摘要：采用公用电压外环方案, 实现了三台1KVA 基于高频零电压开关静止变流器模块的并联输出。三台静止变流器模块均为电压、电流双环控制, 通过公用电压调节器稳定并联系统的输出电压及频率, 同时产生统一的模块电流给定信号。各并联模块工作于电流跟踪壮态, 从而实现各航空静止变流器模块的均流并联。该并联方案仅有一条均流控制线连接且无须外加均流控制电路, 不需要输出隔离变压器以及复杂的均流控制电路,具有简单可靠、均流精度高、体积小、重量轻和组合方便等优点, 可以有效地提高航空静止变流器的可靠性、可扩展性及可维护性。 叙词：航空静止变流器 并联 高频软开关 Abstract：With the using of the common voltage loop control, the parallel out of three 1KVA ZVS-based high-frequency static inverter modules is achieved. Three static inverter modules are all voltage, current dual-loop controlled. The common voltage regulator is used to stabilize the output voltage and frequency of the parallel system, and produce a unified setting signal of the current module at the same time. The parallel modules work on the current tracking state, and then achieve the current equalization parallel of aviation static inverter modules. This parallel solution only need one current equalization control line and no additional current equalization control circuits are needed. And it also do not need output isolation transformers, as well as complex current equalization control circuits. This solution is simple and reliable, with advantages of high current equalization precision, small size, light weight and easy combination. It can effectively improve the aviation static inverter reliability, scalability and maintainability. Keyword：Aeronautical Static Inverter, parallel, High Frequency Soft-switching
