Built a 5hp idler 3 phase converter with start and tuning capacitors.
I did not have proper start capacitor so I used an old method of connecting two 500 microfarad 450 dc working volt capacitors back to back to provide(in effect) one unpolarized capacitor of approx 500 microfarad 450 volt rating. Back to back means connecting the positive terminals together and using the negative terminals as the unpolarized capacitor. Works fine but for how long?
Does anybody out there have the knowlege or experience to predict the outcome of my experiment?
