Actually, I did it. ..

Even the control program does not need to be distinguished, but the energy flow is a positive direction and a negative direction. ...

There is no difference between the two, just defining the direction of current.

There's no need to distinguish ... it's the same ...

My understanding is that after diode rectification, the PWM inverter is connected to the grid or driven.

The front-end diode rectifier adds an APF,

You will use DSP to control inverter and APF.

Is that what you mean?

I don't understand what a PWM generator is. ...

DSP has several groups of PWM output ports. If you need to output anything, just change the relevant registers. If I remember correctly, for example, 28335 and 28 12 should both have 12, and there are four groups. ...

There is definitely nothing wrong with the PWM output.

The power of APF can't compare with your inverter.

Different types of pipes are used.

The drives should be different,

Of course, if you use the same converter,

The drives can also be the same.

The control algorithm is definitely different. The algorithm of APF is mainly aimed at the third, fifth and seventh harmonics.

The inverter mainly considers the energy output.

However, it should not be a problem to complete the above functions on a DSP hardware.

The main consideration is whether the main cycle time is enough. ..

It's software, not hardware.
