工程经济串讲，关于工程经济自考的资料，对正在自考的人也许有用，所以上传上来啦！(Engineering Economic Chuanjiang, with regard to engineering economy Zikao information on the person being Zikao may be useful, so upload the Laila!)

This project consists of two back to back pwm converters used for simulation of traction load in normal operating mode. The first side is connected to a single phase network and uses hysteresis current control. The second side is connected to a three phase network and uses space vector modulation for controlling its inverter.
