Hi... here is the VHDL language...
for adder: sum<=a+b;
Multiplexer (4-bit) :
begin
process (sel,a,b)
begin
if (sel='0') then
y <=a;
else
y<=b;
end if;
end process;
end logic;
And i'm not sure for the shift register...but i know the VHDL language for shift and...
measure power losses...
Hiii everybody,
Have anybody here knows the method to measure power losses for High Pressure Sodium Vapor (HPSV) ballast?
Please help.

Re: How to test SIDAC?
Dear VVV,
I include here the circuit connection for you to check. Also, i would like to know the resistance value for power resistor should be.
Thanks and many regards for your support

Re: How to test SIDAC?
Hii...
could you please see the attachment file for power resistor datasheet?? i would like to know if this kind of power resistor is suitable for my case...

Re: How to test SIDAC?
Hiii…. I have try as you recommended. But when I’m increase the voltage to 200V, the both resistor were suddenly blow up!!! Hehe… also have a flame on it!!!… So, I include here the circuits for you to check just to make sure it won’t happen again. The circuit also shown...
why igniter is required for hpsv lamp
Helloo....have anybody here knows about Superimposed ignitor for HPSV lamp???
If my explanation is not quite details please ask...

Re: How to test SIDAC?
Thanks a lots VVV... your explanation much more clear now...
But, how we can get to know the SIDAC is turns ON or OFF? or are there any method to indicate the SIDAC is turns On or OFF?

Siti
Re: How to test SIDAC?
Thanks for the test procedure. But honestly, I still not really understand about it. I think, I still not understand the meaning of breakover voltage, blocking voltage, peak of state current at Vdrm, continuous on state DC or RMS current, holding current and peak on...
How to test SIDAC?
Hii...
I have a SIlicon Bilateral Voltage Triggered Switch (SIDAC) in high voltage lamp ignitor application. So i would like to know how to test the functionality of this components. Please help me!!. Below is the characteristics of the SIDAC:
Model: K220
Breakover...
