i would like to ask what are the difference between the conventional and inverter compressor?
i know that inverter compressor can vary its operational speed, but the conventional one cannnot.
however, in addition to their applications and control methonds, how they are different, especially for their structural point of view? are there any devices in the inverter compressor that are absent in the conventional compressor?

furthermore, if i connect the conventional compressor to an inverter and replace the pulse width modulation control by vfd control, then can i acheive the same effect as the one of inverter compressor?

thanks for answering
