sg3524

hi friends

I need schematics of 1kva pwm inverter(not switch mode) using SG3524 or SG 3525.
thanks in advance

javed
 

pwm inverter

please specify your spec like i/p and o/p ratings

pwm inverter schematic

for 1KVA you need 24 v or more input volt you can use sg3525 to drive mosfet and a 9-0-9 v 230v 1KVA transformer if you nedd to regulate output
 
sg3524 pwm circuit

Here is a Schematic of a APC UPS which uses 3524.

Enjoy!

thanks darla1,

I need input 12vdc, output 220vac 1000va 50Hz ups with battery charging system.
I hope you will help me.

thank u so much Awarapunshee,

Nice circuit. I am from Islamabad. From where u r?
If u have more schematics please send it to me.

sg3524 pwm

Dear Kg300

Can you tell us please in which format Sch.rar file is?. because when I unzip it, it is sch.g unable to recognised.
 

sg3524 power inverter

Hi,
please where is the schematic for it?
 

sg3524 drive mosfet

i built a square wave inverter with feedback and pulse width modulation using SG3524. i have been using it for 2yrs+. it annoys me because it can't power my fan and hair clipper. infact it has problem with inductive loads. but performs well with other appliances like pc, lightings. it is now obvious that i need a sinewave form. i heard that SG3524 can be used in sine wave inverter. please, anybody with idea on how to achieve this? pls share. my email : doc.code[at]yahoo.com.
 

sg3524 ups

KG300 is not available.

Pls anyone post home UPS cum Inverter 500W capacity (by i/p 12V/150Ah Lead acid cell and o/p 230v) using SG3524 and also low voltage charging.

If use trickle charge method or auto charge cutout is also applicable.

If anyone at least help me by schematic diagram to understand step by step switching technique how switchover in battery supply ( btwn 2ms that is no interrupt the PC) when mains is fails and when mains comes it charges the battery.If discussion with SG3524 , it will be better for me.
Thank for all type discussion.
 
apc sg3524

hi can anyone help me in designing the hardware of the inverter(capacitor bank and ac filter and igbt driver)
thanks
 
SG3524 pwm inverter

if anyone still needs a SIMPLE SG3524 Circuit that can handle up to 5000watts off 12volt 24volt to 48volt PM me i will give the circuit diagram but the transformer for this is a expesive thing to get.
 

Re: SG3524 pwm inverter

HI Friends: Need your help..................

I am designing 4KVA inverter the input is 400V DC...........and the output are 120v DC & 120 V AC.......the 120v AC design is almost complete but 120v DC is creating problem.......

The buck converter i am designing with N-channel IGBT is creating problem .... the output is not stable and the driver ic is IR2113 single channel .......can any one tell me or recommend me any best possible solution my output of buck are 120v dc with 40 Amp load.........can any one help me in providing the formulas for the designing of IR2113 with n-channel IGBT, the value of Bootstrap capacitor and inductor in buck converter........
waiting for ur respone.......

Regard's
