power_active_filter.rar_12 pulse rectifier_IGBT/Diode_capacitor_

The circuit models a standard shunt AHF with IGBT inverter and series inductor on the AC side and DC capacitor energization. The load consists of two diode rectifiers which are phase-shifted by 30 degrees. The Delta-Y connected rectifier is connected after 10 cycles to change the load 6-pulse to 12-pulse. The AHF uses a PLL to generate a reference sinusoidal source current which is in-phase and has the same RMS gain as the load current. The current error between the load current and the reference current is generated by the IGBT Bridge through hysteresis switching. The AHF aims to inject this current error at the point of common coupling in order to match the source current as closely as possible with the reference current.

这是一个关于Python代码中的错误信息，具体是关于导入`pygame`模块出现了无法解析的问题。建议检查一下代码中是否正确安装了`pygame`模块，并且是否正确导入了该模块。如果都没有问题，可以尝试在代码开头加上`from typing import List`这样的语句，或者在配置文件中进行相应的设置以解决该问题。
