The second part is to design the sinewave networks circuits which is composed of sinusoidal current source array and switches, current to voltage converter (I-V converter), two staged LPF, etc.
二是正弦波网络：主要包括正弦量化的电流源整列和开关网络，电流电压转换器，二阶低通滤波器；

In this control law multi-object function is created, which enables a voltage-source type inverter to produce a near standard sinewave with a minimum switching loss.
