I had discussion with my supervisor. The input to the pre-regulator is 160vdc and will have 100W of peak output power.
1)I plan to use a Buck converter to step down to 80vdc with 1A current. Hence, a
DC input supply.
2)The output will regulate the linear regulator to produce 76vdc to...
my input voltage should take up to 160vdc. There is a variable input range for the preregulator. Hence, i am looking at design a DC input into the preregulator.
However, i cant find any circuit that can take in a voltage that is up to 160vdc.
Should i add some circuit in front to magnify the...
Hi Bro,
I am still unsure.. What are the actual differences between a Switching regulator and a Switching Pre-regulator? I need some theories on this. Any website that i can refer to? Thanks.
Hi Bro,
The aim of building the Switching Pre-regulator is to minimize the power dissipation in the variable linear regulator. It must also maintain good line regulation.
From your post, i should consider using a Buck-Boost converter as my linear regulator is to have variable voltage outputs...
Hi,
The input voltage of the Switching pre-regulator is to operate up to 160Vdc and supply 100W power. The pre-regulator must monitor the output voltage of the variable linear regulator and maintain 2-4v across the input-output of the linear regulator. To minize power dissipation in the linear...
Hi Bros,
I am designing a switching pre-regulator to monitor the output voltage of a variable linear regulator. I need some help on this. What is a switching pre-regulator? Is it the same as a Switching regulator?
The pre-regulator is supposed to operate up to 160vdc and supply 100W of output...
c8051f120
Hi,
I am using C8051F120 as the microcontroller for my Elevator Control System project. I am seeking advices on how i can configure the I/O ports to be analog and digital inputs. There is a Configuration Wizard 2 program but i do not know how to use it.
Are there any references or...
mixer circuit design
Hi Bro,
I am currently taking a RF module and is stuck with designing a Mixer circuit.
The RF input frequency will be 105 Mhz and LO frequency is 110Mhz. I need to get 5 Mhz IF frequency. I am unsure how to start tackling this design. Any bros can advise me? I really...
i got to know this formula,
the current use input into the electromagnet. is it calculated using this formula?
EF= C(i/x)^2
EF = electromagnet force
when the electromagnet force is equal to gravitational force meaning at equilibrium point. the current calculted from the above equal is the...
hi bro, do you know where to find info for calculations like what is the amount of current to input into the magnetic coil to levitate an object? is there any formula to calculate magnetic flux using the weigh of the object to be lifted?
thanks bro, the file is relevant for my research now. however, it doesnt say how they derive the number of turns and the amt of current they needed.. no formulas written.. i guess its by trial n error right?
