Hi from Belgrade, capital of Serbia! I have a question - how to make current regulation for half bridge (schematic is in the attachment) from 0 to 30 A, for high current car battery charger 12 V / 30 A max. Output voltage is not regulated, only current. The idea is only to connect SMPS as a batt...

Hi everyone, I'm trying to modify electronic transformer to work without minimum load, which is for this device 105 Watts, and maximum load is 12V/160 Watts, chopping frequency is about 30 kHz. Greetings from sunny Belgrade!

Hi to everyone! I want to make buck converter as lab power supply, it has to be with voltage and currrent regulation. Voltage source is a classic 50 Hz transformer from 230 Vac to 35 V dc /5 Amps and then is connected to above mentioned converter. I have a schematic with MC34060 chip but it has...

Hi to everyone on DIYSMPS! I want to make SMPS substitution for 230 VAc VARIAC (regulated autotransformer from 0 to 300 Vac) with some kind of buck-boost SMPS converters - one for positive half of mains voltage and one for negative half of sinusoidal mains voltage or to make this device with two...

I have a problem to make forward converter - it works good with lamps load:four halogen bulbs 12V/50W and one car bulb 12V/20W connected in parallel, and I adjust the duty cycle with trimmer and everything works fine (power consumption from mains is about 0.75A).But problem is that converter...

Hi, I have a problem to build power supply - starter for cars and trucks and my idea is to build SMPS starter,some kind a cheap version like electronic transformers for halogen lamps but for much more power like 2 or 3 kW.Is anyone is willing to send me a schematic for this purpose?Here is...
