    Resonant PLL Circuit

    HELP!!! so, the thing is that i have been trying to build a resonant high frecuency circuit to control a variable capacitor, this capacitor can support high voltage and high frecuency but its variable due to the electrolite it contains.. so I have been tryin to desing it and have come with a...

    Analog or digital self-tuning quartz crystal oscillator

    Hello everyone. I'm a rudimentary electronics enthusiast --i.e. I'm at all well versed in theory--. I've built a few utilitarian PCB's and circuits. In the same utilitarian line, I came across a video on youtube (in Spanish) where someone demonstrates a picogram electrobalance based on a quartz...

    Low frequency oscillation induced during CCPS discharge.

    Hello all, I am designing a CCPS and using a phase-shifted, series-resonant bridge as the switching topology. There is a DC block capacitor in series with the transformer primary winding. When the target voltage is reached, the H-bridge switches are turned off until a command for the next...

    Capacitor calculation with real and imaginary parts for a resonant converter

    Hi All, I have designed a resonant LCC converter for my thesis. It has been some time since I visited the theory and believe I used the following document by Robert Steigerwald to select the resonant components: IEEE Xplore Full-Text PDF: I was attempting to rearrange this equation for the...

    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...

    Active Coupling

    May I ask how do we coupling the two identical resonant circuits by using transistor?
