MOSFET Gate Driver Circuit in Proteus | Buck converter | IR2101|

[@LS-oh6po]

Hello sir, is it possible to drive 3-phases bridge using IR2101 ? Thank you

[@munaemhashmi4481]

I am using ir2104 and i am confused because of Sd and In pin where to connect plus i am making it for BMs kindly guide what will be the load

[@minhtran7096]

Is there any particular formula to calculate the capacitor and resistor value?

[@ineskhaldi549]

You find?

[@the-beneficiary1809]

What do I do If the power going to the mosfets are 120v dc, and the mosfet gate drivers are using separate 12vdc. How can Vs on the gate driver connect to that high voltage on the mosfet shouldn't they not be connect and stay isolated what connect to Vs on the mosfet driver then beside the bootstrap circuit capacitor from VB?

[@moddyblues7120]

hey man, can u explain why C2 is 4.7uF? ty

[@dr.haiderzamanlecturerelec7737]

C2 must hold enough charge to turn-on high side MOSFET. It depends on duty of high side mosfet

[@dr.haiderzamanlecturerelec7737]

I set that roughly, can range from nF to few uF

[@biniambrhane6818]

can we use the same circuit to drive three phase inverter i mean six MOSFET

[@dr.haiderzamanlecturerelec7737]

Yes! You can need three driver ICs in that case.

Hi doctor i don't have model ir2101 in isis.Can you send me this library thanks.

[@fihtednight6723]

what if just use just the hight side does that work ??

[@dr.haiderzamanlecturerelec7737]

We are driving two MOSFET here, the one with floating source terminal is driven using high-side while the other having source terminal connected to ground is driven with Low-side drive. If you have one MOSFET to drive you can use either the high or Low-side driver depending on the source terminal connectivity.

[@rendymuhammad8090]

Can we use lower spesification for rlc compoents?

[@dr.haiderzamanlecturerelec7737]

Use RLC relative t switching frequency.

[@rendymuhammad8090]

What is the value of RLC components if we use 50hz frequency?

[@ineskhaldi549]

​@@rendymuhammad8090did you know the value of RLC components please?

[@selmanmegoura5467]

hi sir.What would happen if we chose only one input and one mosfet !!!!

[@dr.haiderzamanlecturerelec7737]

You can leave one side floating. Either use high or Low-side driver is fine.

this is a synchronous buck converter

Yes this is synchronous buck converter, the low side device is a mosfet
