采用LTspice的4端口模型 基于图5所示的经过改进的平均模型构建了一个4端口模型。在闭环操作中,这个4端口模型可以使用标准的电路分析程序(例如免费的LTspice)来分析PWM拓扑,以确定DC和小信号特征。 图8显示了使用LTspice对各种拓扑实施模拟的模拟原理图,对每种拓扑都使用相同的模型。图中未显示反馈电...
Circuit - level modeling involves representing the AC constant current source as a combination of electrical components such as resistors, capacitors, inductors, and active elements like transistors. Ningbo Zhimao's engineers use circuit - simulation software, such as SPICE (Simulation Program with Inte...
In LTspice, AC analysis involves computing the AC complex node voltages as a function of frequency using an independent voltage or current source as the driving signal. The small signal analysis results are plotted in the waveform viewer as magnitude and phase over frequency. AC analysis in LTsp...
The ideal sinusoidal AC voltage is adopted in LTspice software and applied to the proposed circuit. However, the sinusoidal source is replaced with a PG in the experiment. The applied sinusoidal signal to the proposed FBRJT and the rectified voltage at the load capacitor, CL1 (Mode 2), are...

But it can put out as 5W or so without overheating or current limiting. In troubleshooting the problem, I got the LtSpice LT1533 simulation fixture working. Of course it doesn't go into thermal shutdown like the real circuit does. I modeled the output transistor power (Vcola *Icola) and...
You can clamp to the MCU supply rails as long as its well decoupled at the clamping point and the total load current of the supply rail is greater than the clamping current. I've modelled the pulse in LTspice, with a control voltage for amplitude and parameterised period and pulsewidth se...
I've uploaded simulation in LTSpice. @Kammenos: I don't know what outputs the LDR, the single thing that i know is the resistence that changes with the light. At 8 November 2011, 8:26:22 user Kammenos wrote: [reply @ Kammenos] @Alex what is the LDR output? Voltage or current?
LTspice Simulation The load is set up as a Behavioral resistor, demonstrating an “undocumented” feature of LTspice. The resistance is inversely proportional to a pulsed CTRL voltage source with slow rise and fall times, to ramp the AC load current up and down. ...
A quick check of the AD8237 noise and ADA4505 noise determined that the AD8237 is the dominant noise source. Figure 3. An LTspice schematic. Figure 4. Transient simulation results. Figure 5. Transient simulation results zoomed in. Figure 6. AC simulation results. ...
