UCD 25 watts to 1200 watts using 2 mosfets

[stewin]

use t-106 26 yellow core with white strip from old computer power supply.

coil
>>>> 30 turns of 16awg wire length of wire 1.1mtrs

 

[manojtm]

Hi stewin,
why you need 16awg wire for lc meter? 82uH coil you can purchased from electronic shop it is ready available.

LC meter

here more updated LC meter i also made and it works well
small 100uh coil can be found on defective tv or psu

 

[stewin]

cool . thanks irvynejay for sharing

CIRCUIT OF SMPS WITH MODIFICATIONS

new detex smps layout

 

[pergo]

i made this driver board for UcD style class D.

It uses LT1016 for comparator, MPSW92 for level shifter, and IR2010/2110 gate driver.


ps: in the image I need to mount the feedback network and the +-5V regulators for the LT1016.

hi mr manojtm
can you share more clear and beager files for pcb and shematic off AUD600 please?
thanks

Hi Hadighorbani,

Ok i will do this is the clear pdf (1:1)file with some part modified you can use this

Regards
MANOJ

 

[stewin]

thanks manoj finally you've shared.


hi guys, i have these cores i think they're E65/62 cores can they work with a IGBT30n60d to produce over 5kw power? I found them in an old ups as inductors.
please help.

Hi stewin,

thanks stewin

IRFP4668Pbf worked with fsw=250KHz resistor = 10 Ohm but THD is High %

[manojtm]

Hi all

work very good IRFP4668 resistor = 4.7 Ohm or 8.9 Ohm (parallel 10 + 82 ohm)

pls give the programmer schemenatic

here more updated LC meter i also made and it works well
small 100uh coil can be found on defective tv or psu

hi, greetings,
first fo all thank you for share the lc meter share schemantic i am intrested in, i search internet about pic programmer but lot of schemantic so i confused. pls share the programmer schemantic.

very thanks for pdf friend

hi again mr manojtm
can you please share part list of your amp and swichin power?
it is important beacuse i do not know which of resistor are 1% for example and some of part is unknown to me.
very thanks friend

Hi Hadi,

all resistors are 5% except ** one (1K 1%) you can vary the value ex: 1K or 820 Ohm or 680 Ohm or 560 Ohm or 470 Ohm. lower the value will increase the fsw. NB:keep in mind your MOSFET(low switch ON,100nC and high speed switch) will support the high fsw.

LC value also vary when you change the fsw ex: 500 Ohm resistor L&C will be 33uH & 0.47uF/250v (fsw = @400KHz)

IR2110 pin 5 & 6 connected capacitor is 1uF/100V.(type mistake 10u/100v)

and snubber 47 ohm 0.5W with 100pF/1kv,MUR1560 & 25uH coil is an optional ( it is for EMI reducing)

MANOJ

and ETD29 have gape or not?

Hi irvynejay
Please send pcb bridge amplifier that in hte picture

If anyone wants to test the modified IRSK4.5 board(#2731) in the board-12x TO220
Warning board has not yet tested!

Hi Nano
greetings any idea of core used in smps the round one with yellow tape and what core material please can you help out
warm regards
