Thanks horace1, but I find it hard to understand the information I got from your links. What I need are S.H.E ICs to generate sine wave for inverter. Single Harmonic Elimination.
I want to know the various ICs that can be used to generate pwm sine wave. I was able to get one on google but not with much design support. HT1112 IC. Please help me out. I dont really want to deal with programming microcontrollers as I do know they can be used.
. yes, am refering to inverter (AC). There is no choke in the designs have been seeing. am still wandering about the difference

I am into inverter design, I noticed that when a fan is connected, the speed is usually low. My oscillator is an SG3525 IC, I have seen several designs using the same IC with same configuration but when a fan is connected, it rotate very fast though still buzzing, I removed the filter cap from...
hello everybody, i discovered something, i dont usually scrape off the flux after soldering which can form little capacitance, it might be nothing, but.between drain to gate can be catastrophic. I have corrected that and it(the power supply) has been ok since den.
some of them(smps) had this problem. The first time just the fuse, second time the FET. And in another case, the IC (FET inbuilt) blew up, changing the IC, it blew again after pluging in the next day. its ICE3BR... from infenion.
The mains cap is 47uf. besides if the capacitance is much, it can only destroy the fuse not the FET and it driver. Maybe my problem is dv/dt related, thought these ICs are designed to tackle that.
Thanks. I dont really know what flux is, what am talking about is some kind of yellow coloured glue which goes molten during solderimg on PCB boards. By the way, what do you mean 'low level circuit'?
Sometimes after soldering of points on PCB, yellow gums do 'emerge' from the board, most hobbyist do scrap them off, but i don't even in high voltage applications. Can they conduct electricity in high spikes if they are touching two points?
I repaired a power supply (laptop adaptor) and it was working fine, next day i tried testing and it blew even after working fine. it utilizes UC3842 and a FET. lately i also repaired a dvd player power and it was okay. during testing after a short time of power off, it blew up while trying to...
