摘要
针对当前高压大功率变频器在预充电技术上存在的不足,对其进行了改进方案的设计,提出了一种新型高压大功率变频器的设计构想。该新型变频器具有更优的预充电功能,无需高压开关,调试方便,操作性好,有着更好的系统可靠性和安全性,成本低廉,便于广泛应用。
in this paper, we have a technical improvement for the current pre-charge technology of high voltage and high power inverter and propose a new type of high voltage and high power inverter. The new high voltage and high power inverter has a better pre- charge function, no high-voltage switch, convenient debugging, operability is good and it has a better system reliability and security, low cost and easy to wider application.
