1)i get my HF transformer from my old power supply
2)i don't know how to design a HF transformer
3)i may use heavy low frequency transformer but can i use it in my condition (12/220 transformer "this means that if the output load take 1A, A 18.33A will pass through the 12vAC side")
4)i will not...
thanks all
1) in case of using 12vDC/12vAC inverter then stepping up the output 12vAC to 220vAC using transformer
this means that if the output load take 1A, A 18.33A will pass through the 12vAC side
Are there any transformer that can withstand that condition??
2)for the boost converter
Can the...
hello
i am making an 12vDC/220vAC inverter
i use two ICL8038 function generator ICs to generate sin and triangle wave the i compare between them using a comparator as shown
any notes about the image ??
1) i want to know how to use this output signals to drive the HIN and LIN pins in the...
thank you FvM
i try to build my own circuit and it work well
I want to turn on the high side MOSFET for a long time , but it turns off due to the discharging of the bootstrap capacitor
i want to know about the charge pump technique .
can you help me??
thank you in advance
hi FvM
can i connect the VDD pin to 5v logic voltage?? and can i connect the Hin and Lin directly to the PWM pins in my AVR microcntroller??
thank you in advance
as i already have some of them
previously i was made the h bridge by two low side N channel MOSFETs and two high side P channel MOSFETs as in the Figure
but there is a problem that this circuit is only for supply voltage equal 36v so for any supply voltage there is a different circuit...
thank you for replay
I can not find this IC
i found IR2110
i want a schematic to drive MOSFETs with this IC
can i use P channel MOSFETs in the upper part of the H bridge??
Are there any advantages to do that??
thank you in advance
thank you for replay
1) OK, i want to know a number of high side driver that i can use with ICL7667 low side driver to make the H bridge
2) If i use the high side transistors as P channel MOSFEts like IRF9520 can i use only the low side driver to drive the high side and low side MOSFETs ...
thank you for replay
i want to make H bridge with 4 IRF740 N channel MOSFETs and the ICL7667 driver IC
please i want a schematic of the circuit
thank you
than you for replay
Yesterday my friend bought a driver for me
it is ICL7667
i want to know how to use it
i want a schematic of the driver with 2 N channel MOSFETs
which IC can i use ?????????????????????????????
which IC can i use ?????????????????????????????
please i want to know which MOSFET driver IC can i use
there are a lot of ICs such as LTC4447 , IR2184 , IR2112 , .............
according to what can i choose??????????
i will use N channel MOSFET...
