    how to get approximately 30V on Vout in this voltage source?

    hello everyone. i´m doing a voltage source and i want to get approximately 30V-500mA on Vout with the smallest ripple as possible. : i got a transformer 12 0 12 V and a 1000V 2A bridge rectifier and 4700uf 35V electrolytic capacitor. The thing is: after rectifying it it should give me 24 *...

    Powering a DC Motor using a Bridge Rectifier

    Hello, My treadmill has been sitting around ever since the motor-controller board broke. Since I could not find a replacement for the board, I thought why not build a power supply myself. I do not need fancy speed control; one single speed value is enough for me, probably the value that makes...

    AC/DC converter (110VAC to 12VDC, 120W)

    I'm looking to design a PCB that will have a 110VAC input and convert it to 24VDC output with a maximum load current of 5A. Is mounting the step down transformer on the PCB a good idea? What better ways are there to do it?

    Purpose of a rectifier in a positive oscillating circuit

    Hello, I found a circuit (transmitter) design that would create an oscillating magnetic field. Another circuit (receiver) would pick the induced voltage up and amplify it. Now as I understand it, the oscillating part has only positive voltage. But in the receiver part they use a recitfier. Why...

    Help with basic piezoelectric generator circuit design

    Hello, I want to experiment with the properties of piezoelectric generator devices. I am looking to get a few PZT devices where I can stress / impact the material to produce current. I have concept to use multiple PZT devices where they will be stressed simultaneously. The PZT devices output a...
