I need help to solve this problem.
3 unbalanced impedances of (30+30i)ohm, 30ohm and (30i)ohm are connected in delta.
This delta-connected load is then connected to a 3-phase 173V balanced system by three balanced conductors each with impedance of (0.8+0.6i)ohm.
How to find the current...
Hi..
I am using n-mos, irf3706 on highside and lowside of a circuit.
However, I need a driver to drive both mosfets.
I have this driver, IR2101(high and low side mosfet) and IR2117 (high side mosfet) which need Vcc of 10V to 20V, however, I only have 5V.
Can anyone suggest me a better...
Hi Sprooch,
I need your help. I'm designing buck/boost converter. Can I know what type of inductor u get for ur cct? Also the mosfet driver connection is the typical connection shown in the link of the datasheet IR2301? By apply PWM, the mosfet will work?
Hi,
I am using a mosfet driver, IR2106 to drive my n-mosfet on both highside and lowside. Is it as refer to the datasheet of IR2106 circuit, both my mosfet will work? What else can it be wrong?
Hi FvM,
The circuit can't work. If the power supply is 12V, then how much power I need to power up the op-amp? It must be greater than 12V. I can't use external power supply. How do I power my op-amp then?
It will not work if I use 5V to power op-amp and with power supply of 12V.
Hi,
Using an op-amp, with the above diagram, is it possible to turn the op-amp on and measure the current which Vcc must be greater than Vin? How do I make Vcc greater than Vin if my maximum Vin is 12V else my op-amp cant operate. I need a single rail op-amp since I got a ositive output. Can...
Hi,
I need help with my design of single rail op-amp to detect current.
With input range of 1V to 12V into the op-amp to detect current not exceeding 3V.
As I know that I require higher voltage than 12V to power up the op-amp if the input to the op-amp is 12V. How am I able to operate the op-amp?
Hi kekon,
Can I check with you regarding the 4 different transfers (control, interrupt, isochronous and bulk)? I dun really understand... If possible, can u explain to me.
Thanks.
Thank guys for ur reply.
I am designing the non-inverting buck-boost converter with input 5V and 2A which gives 10W.
But I require to design an output of 1V and limiting the current to a maximum of 3A. How can it be design?
Regarding the Rsen, is it jus normal resistor will do?
Hi...
If I'm designing a high side current sensing of single rail as shown in the attached doc. Will it work?
How is the current measured from the circuit and feed into ADC and also what type of resistor should be choosen as the Rsen?
Thanks.
