    [SOLVED] ir2110 output problem

    you can use sg3525 and ir2110 for a solid state tesla coil. be careful, high voltage is dangerous.

    h-bridge inverter using ir2110

    do you consider these? and uf4007 is absolutely better for this

    [SOLVED] Half bridge low current

    today i have connected a 10 ohm resistor instead of short circuit like this: then the result: i think everything is fine according to my calculations the current must be 0.35 A for this situation (10/2=5, 5/10=0.5, 0.5/(2)^0.5=0.35 A) there is 0.24 A, i think 0.11 A mistake is due to solder...

    [SOLVED] Half bridge low current

    thanks a lot, but i do not have enough time for this certainly. i wonder only: can you say me if i use solder tracks instead of the cables would be better?

    [SOLVED] Half bridge low current

    so interesting. my short circuited load was like this (two thin cable which have roughly 30 cm length) then i replaced my short circuit like this (i disabled the cables) then the result: there is current that was searched by me for weeks! the question is that: can two parallel cables were...

    problem in H bridge hardware implementation

    please scrutinize this. i have a half bridge and i do not have any Vgs problem

    problem in H bridge hardware implementation

    do you consider these

    [SOLVED] Half bridge low current

    Also same stuff is occuring in very wide frequency range (from 80 kHz to 400 kHz) it seems like there is a very high inductance but there is not anything like this. very interesting.

    [SOLVED] Half bridge low current

    If we ignore rheostat with short circuited load the current must be very high not 3-4 A.(with 20 V) therefore i think the problem is not load

    [SOLVED] Half bridge low current

    this is a video about load voltage(source of half bridge is off = 0 for this situation but sources of sg3525 and ir2110 is on) i am changing the frequency of the sg3525 and load voltage's frequency is changing also. this is interesting. i think the voltage of the load must be zero for this...

    [SOLVED] Half bridge low current

    i could not understand what do you want second video shows voltage waveform of the load (between its ends) load is a rheostat in this situation. for 3A its resistance value must be adjusted to very low values. there is another point: when resistance value is extremely low then if i increase the...

    [SOLVED] Half bridge low current

    i really wonder the reason, if there is an open circuit how can voltage waveforms become true or how can 3A current flow with short circuit? i can not imagine anything this is an unusual problem i checked many place by a multimeter against open circuit (by measuring resistance) they looked...

    [Moved]: at resonance, is the circuit is stable?

    is there a possibility like r<0 ?

    [SOLVED] Half bridge low current

    a rheostat roughly like this but same result is occuring without any load (with short circuit)

    [SOLVED] Half bridge low current

    and also i will try this to reduce inductances of the parallel wires
