But how do i keep the current constant.The current is boosted everytime the voltage is bucked.Added to that is the issue of dissipation.
I can do this:Use an LM317,get a constant voltage and then give this constant voltage to a transistor to get a constant Ic.But severe dissipation problems.The...
I need to design a constant current LED Driver of 1A to drive an LED array (Green) 3 in parallel and 4 in series.
"The input voltage will vary from 16 to 32 and irrespective of this a constant current driver is to be designed.
1.I had tried using linear circuits-LM317,where there was too...
Yes ,want both the ac voltages 28 as well as 115 @ 400Hz with a 28 volts DC input.A static inverter to be precise.How do i go about it?A sine wave or a quasi sinewave is what i require.How would the circuit diagram be?
I want to design a 3 phase inverter with the specifications as
Input dc Voltage :28volts
Output ac voltage (dual) :28volts and 115volts @ 400 hertz
I'm new to this and unable to figure out how to design an inverter for this specification.
If i use a normal 3 phase inverter with 28volts dc then...
Well for a 1kw design ,100V and 10A at the input,so at the output say around 20 A and 40V ;the power is to be conserved.Is the power conserved in a DC-DC converter???
I'm trying to create an electronic circuit based on the property of
ELECTRIC ARC (DC)which exhibits a decrease in voltage with an increasing current.The power is to be conserved,
SO trying to design a circuit where i give a constant DC supply and enable the circuit design such that my output...
I'm trying to simulate a BJT circuit on MULTISIM(BC635) .What i require is to provide an input DC voltage of 50V ,create a BJT circuit such that my voltage at the output is stepped down or rather the current at output > current at input.SO essentially if i want to build a circuit where i want my...
Vo= 120@ 14A is just an estimation to the set of values mentioned to help understand what i exactly need.
The purpose for me asking this is i've taken baby steps to working on an arcjet thruster load.What should be done is:
1.Designing an electronic load such that it gives me an output...
m trying to simulate an electric arc using non-linear active load on NI MULTISIM or PSPICE .The electric arc is such that the current increases as there is a decrease in the voltage;when plotted on a graph we have a negative resistance slope,an exponentially decreasing voltage with increasing...
If say Vin =130V,the circuit should be designed in such that at the output Io increases with a decrease in Vo.The graph is plotted with Vo against Io,which is an exponentially decreasing curve of Vo Vs Io.
Eg:
Vin=130v;Vo=125v;Io=10A
Vin=130v;Vo=122v;Io=11.5A
Vin=130v;Vo=120v;Io=14A...
want to design a circuit on NI MULTISIM which is like:
The input voltage of around 100 to 150 V and input Current 10A;
The circuit designed should be such that at the output i need an increasing current with the decrease in voltage;in other words the motive behind the circuit design is to have...

I want to design an electric arc simulator(electronic load) .A sub circuit of this involves the design of a trans conductance amplifier with an IGBT. I do not want an OP-Amp based trans conductance based circuit,i'm very specific on using an IGBT for the transconductance circuit because i...
I want to know the basics on how to bias an IGBT??How do i calculate the drain resistance .source resistance and other values for a particular IGBT?I have surfed quite a lot.Could not find appropriate and sufficient information.
I saw the link that you sent ,much earlier. I guess you did not go through it.The datasheet itself says MC1494 is now "OBSELETE" ,not in use.Also i'm looking for an equivalent of the same(MC1494) on NI MULTISIM.
