Can you help me with some circuit specs? Answered
I am planning to build a driver control system for a variable speed DC motor. My initial design has shaped up as follows: AC voltage from a wall plug to a full-wave rectifier with a four diode bridge and a T or Pi output smoother. The rectifier would then be connected in series to the motor and a potentiometer, like a dimmer switch. Now the part that has slowed me down, the voltage range for driving the motor is 0V to 120V DC, which leads to the question. If I took out the transformer that is normal seen in a rectifier circuit to keep the higher voltage, what sort of specs would I need for the diodes, capacitors, and inductors in my circuit? Or is there a better way to obtain the desired Voltage range from an AC wall plug with out buying something costly?
