Re: draw double amount of current from multiple ac-dc-adapte
Thank you Platonas~!
1. Do you mean it's ok (even though not 'BETTER') to connect adapters in parallel without diodes?
2. Are you sure this combination will provide 4 times of 4A = 16A current?
Hi, i'm fixing dc-ac-inverter. But wants to do the job in the room, not in the garage while car engine is running.
Now i've got 4 ac-dc-adapters with 12V 4A output.
Is it possible to draw 12V 4x4=16A by connecting 4 adapters in parallel?
If ok, do I need to add schottky diodes to keep from...
Would you show me some idea of the substitutes for this part?
In my case, I can find 40A fuse very easily in my place. What if I parallelise 2 40As to replace 80A for awhile?
Thank you , Echo47~!
I messed up with the power circuit by powering in reverse to the inverter(chk this post i uploaded: ). Fortunately I repaired it by help of Echo47, but realised one of the fuse on the power switch system has gone, and it will take more than a week to receive the part, so that now i'm asking if...
Thank you so much , Echo47!! It really helped me!!
I requested the quote and will order asap. But until now not sure if it will work fine or not. Will let you know.

Thank you.

Hello,
I just broke 12V-220V inverter by powering to the 220V outlet. It smoked and spartked. I opened inverter and found out one array of two IRL2203N MOSFET arrays to be exploded or burned.
Now I replaced those broken 8 MOSFETs with the same parts, but in the...
thanks! i found the circuit diagram.
but,
R1 = Vbeo1/(Ireo-Io1Bo1) and
Io = Ireg + Bo1(Ireg-Vbeo1/R1)
i don't what Io1, Bo1 exactly mean. I'm afraid i misunderstood βo1 as Bo1..
what do the above variables mean exactly?
thanks, in advance~!
ireg lm7805
hi,
i have LM7805 (+5dcV regulator) and ipaq4150(PDA) which charge its own battery through USB adapter.
USB port at PC has 4 pins: (1)DC+5V (2)data+ (3)data- (4)GND
i thought i can charge my pda in my car cigar jack (+12V) which i make 5V regulating circuit for my pda.
but when...
