Hey. I am crafting a super simple "trash-made" rectifier with a puffer capacitor, for a 220vdc motor.
I tried cabling the "circuit" to the multimeter instead of the motor(in case i mess up something, it is a smaller problem) and experienced that i have to wait about 15-20 minutes before the capacitor drains back to 0 or close.
What might solve my problem? I am thinking about placing a resistor parallel to the capacitor, might it help? This is my current design:
How to choose the wattage and size of the resistor? I'll use a 300w motor from this, it means no problem to my diodes as they are extra durable and hardy, but i am afraid of "overloading" the resistor and putting it to the flames.
