在图15中,在电感上对节点IN和SW之间的电压进行差分探测。在TON期间,MOSFET接通,电感右侧接地,而左侧在VIN处,使得电感上的电压在TON期间为12 V。在TOFF期间,MOSFET断开,电感的右侧置于48 V,而左侧在TON期间在VIN处。由于差分探针从VIN中减去VSW,得到–36 V,但符号现在无关紧要。重要的是电感...

I use TPS25974LRPWR. I have changed the circuit slightly to suit our needs. An op-amp non-inverting amp with gain of 4 is used to derive the current monitor signal from ILIM output. For short circuit simulation, I have added a voltage controlle...
So you are saying that instead of using a wire, you would use, an LCR network to represent the wire (PCB trace) between nodes, a specific LCR network for each wire (PCB trace)?I just wonder then if you know you are always using FR4 1oz 4 layer stackup with internal VCC and GND ...

为了进行测量,控制环路断开,正弦波扰动进入高阻抗路径,同时测量由此产生的控制环路增益和相位,使设计人员能够量化环路的稳定性。 LTspice模拟可用在LED的控制环路中创建类似的注入和测量。图2显示了一个LED驱动器(LT3950),给定频率(f)的理想正弦波直接注入到负感测线(ISN)的反馈路径中。测量点A、B和C用于计算注入...
.model SW1 SW(Ron=10 Roff=10Meg Vt=1.1 Vh=0.1) You need some think like above. Ron is resistance when on 10 ohms. Roff is resistance when open 10 mega ohms. Use help on switch. You may have to add a resistor from the cap to ground so the input has a DC path to some suppl...
And LTspice works even less when trying to use it with my own schematics. I hope at least someone here is able to provide a lasting and working solution, so that rumours do not have to start about the buncb of amateurs working in this particular section of Eagle/Autocad. Report Reply...
