Assuming that I have the right optocoupler, correct phase triggering, and additional smoothing capacitors in parallel with the load (the load is a DC motor by the way). Is the circuit feasible?
Is there a way to reduce the voltage going to the optocoupler's bjt? I only have the 4N25 opto and I may not acquire a more suitable optocoupler here. But I won't force it if there aren't any good suggestions.
Good day
I would like to isolate the control side of the circuit from the power side by using an optocoupler. As shown in the picture below, I connected the anode of the scr to the collector of the optocoupler bjt and then connected the emitter to the gate (with a resistor and a schottky diode...
Thanks for the corrections. These were really helpful and I will gladly consider them in future projects.
For now, I'm just gonna go back and revamp my codes. Hopefully I can fix them in time.
Best Regards,
Jonathan
We were taught logic gates and functions, but I think our teacher wasn't that enthusiastic to teach us further into verilog principles. We were left there to code without guidance. Kinda sad though...
I was thinking of using a case statement to transfer each segment data one by one to avoid the risk of accidentally overwriting before data transfer.
case (count)
4'b0000: seg5=seg4;
4'b0001: seg4=seg3;
4'b0010: seg3=seg2;
4'b0011: seg2=seg1;
4'b0100: seg1=seg0;
4'b0101: seg0=in...
Thanks for the reply klaus.
Actually, the result that I wanted is shown in the image below.
The three boxes in the image are 7 segment displays, each with corresponding registers. I wanted that the data in each register would shift to the left each time a new input is given. However the code I...
Hello all,
Let's say I have two registers declared, namely register A and register B. Both can store 1 bit (binary) of data. If I have an input of 1, register A should store a value of 1. If I supplied an input of 1 again, the data that was recently stored to A should jump to B and the new...
I was planning on connecting the circuit this way: AD, BF, BG, and CH. Node E is connected to all other ground symbols drawn. I was hoping that the transformer would supply ac voltage to the bridge rectifier to feed the power supply and at the same time give the main circuit a sinusoidal wave...
Thanks for replying. I'm sure that the connections at the power supply circuit with a full wave rectifier is correct bit I'm not quite confident with the op amp circuit since I need to feed a sinusoidal waveform to it. The way it should be grounded got me confused. How should I separate the...
Hello everyone. So basically I was going to construct a circuit which is composed of an opamp precision half wave rectifier (bottom part of schematic) and its power supply (upper part of schematic). The left side of the schematic is a center tapped, 220Vac to 15Vac (both in RMS) 1A transformer...
