    LTspice: using conditional statements to switch ON & OFF voltage–controlled switches in a resonance circuit

    Hi, An initially charged capacitor in a resonance circuit undergoes periodic voltage reversal (blue line), as shown below: A possible circuit to address this problem uses 2 capacitor banks & switch modules, as shown: C₁ and C₂ represent metallized film capacitor banks of equal capacitance...

    Modelling this circuit

    Hello Leute, I've been having a hard time with my school project and wondered if you could help me. My task is that I have to modell a circuit of wireless charging (seen on the picture). For help I was given this Wikipedia link and later on I was told by my teacher that my main goal should be...

    can't find definition of model 'MBRA340T3G' in LTspice?

    Hello, I have tried to add the schottky diode(spice model from onsem) as you can see on the schematics on LTspice but I keep getting the same errors and I have watched the intro from this link : Adding Third-Party Models to LTspice IV but I still get this error I have saved the same schematics...

    Unknown Subcircuit after creating a custom model

    I'm trying to model a simple mechanical switch that closes at a set time, remains closed for a set duration, and opens again. I am doing this with a behavioral resistor, but I want it to be clear from the schematic that what I mean is a switch, so I created a new symbol. When I attempt to use...

    LTspice simulation of RLC discharge circuit using voltage controlled switch

    Hi, I would like to simulate the discharge curve of an initially charged photoflash capacitor into a RL load as shown below (with component parasitics): A few things to note: 1. photoflash capacitor (C1) is initially charged to 360V 2. a voltage controlled switch represents a microcontroller...
