I have been working on a 1-Phase VFD design that I think is ironed and I welcome any coments.
I will be using a simple light dimmer as my POT to vary the voltage and I include a sense line to my Frequency generator to vary the frequency. I decided to use a 555 Timer instead of a sq wave generator to generate a frequency signal, then the signal goes into a D flip flop to ensure 50% duty cycle (this however divides my frequency by 2) so the top end of my frequency range should be 120Hz. I then drive 2 pairs of Power MOSFETs. I should end up with variable voltage and frequency.
