2022年8月8日 · Hello friends I assembled this circuit When I measure the output with a voltmeter everything is fine. But when something like a battery or a lamp or a DC motor is connected to the output, the output of the circuit becomes close to zero I have been dealing with this problem for a long time and I...

2009年9月7日 · Hello, I don't suppose anyone has found or already has a SPICE model for a UC2845 or a UC3845 PWM controller? If anyone can help it would be greatly appreciated. Thanks Simon

2012年6月25日 · Hi, I want to simulate a power supply based on UC3854, But I can't find it's LTspice model . Does anyone have it or designed it before.

2017年5月29日 · Hey guys. For a new project I want to control a 8.4v dc source to output 1-~6v 50a or more to a load that, at its minimum, will be ~.04 ohms.. I've got a basic buck convertor diagram that I think will work but I'm grossly lacking in specifics when it comes to actually building it. If I'm honest...

2014年11月9日 · It seems everything works but with low output voltage. After power factor correction section I get 374-380Vdc but I would say that value is correct. I tested output diodes and all of them seem to be OK. Any idea why I´m getting 5Vdc instead of 28Vdc? As PWM controllers I have UC2843 (PFC), UC3845. I haven´t schematics.
