船舶抗负载冲击高性能逆变技术研究

摘要

The characteristics of single⁃phase AC load in watercraft are discussed in this paper. The excellent invert technol⁃ogy which can endure the rigorous impact current coming from 220 V AC non⁃linear loads in watercraft are researched especial⁃ly. The response speed about digital⁃analog hybrid control and digital control is contrastively analyzed by voltage open⁃loop Bode diagram. The feasibility of the excellent invert technology about enduring the load impact on watercraft was proved by the test of a 220 V/10 kW prototype.%讨论船舶单相交流负载的特性情况，重点研究能够承受船舶220 V交流非线性负载引起的强冲击电流的高性能逆变技术，通过电压开环伯德图对比分析数/模混合控制策略与数字控制策略的响应速度，并搭建一台220 V/10 kW的单相全桥逆变电源样机，实验结果验证了船舶抗负载冲击高性能逆变技术的可行性。
