Let the following circuit:
The diodes and SCR are supposed to be ideal, the supply source v(\theta) = V_m \sin(\theta) , let \phi \in (0, \pi) be the angular gate pulse for T1 and \pi + \phi be the angular gate pulse for T2, i want to understand why in the interval \theta \in (0, \phi)...
Hello
I have a DC voltmeter and I would like to design a simple circuit to that can allow measuring the RMS AC voltage on the same meter.
I was wondering if using a bridge rectifier is good practice or does it have any drawbacks?
The voltage range is 0-20Vrms, so:
Vmax = Vrms/0.707
Vmax =...
Hello
I have this problem as mentioned in the subject, which happens when I connect the transformer to a " 3-phase full wave controlled bridge rectifier ".
I have a fully controlled bridge rectifier board of (TYN812RG) thyristors, and I want to trigger it through some firing board which I am...
I have a hydro turbine that generates 3 phase ac, I then rectifier it to run a grid tie inverter, I'm wondering if I should earth the negative output of the rectifier?
I'm new to electronics and decided to learn something new by trying to put together a small rectifier circuit that converts 24VAC to DC. So I put together a little full-wave rectifier circuit that consists of four diodes and an LED and ran into an issue when I tried to measure the DC output...
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 *...
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...
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?
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...
Hello
I'm trying to implement a rectifier and AC voltage sensor. The rectifier part works just fine. I'm able to power my device without any issues.
Please look at C2 in the screenshot (Circuit schematic). This connector is connected to AC voltages. Vin is a rectifier and the DC part is to...
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...
