resonance

Hello everybody! I am trying to design a boost converter using TPS61088 IC. I used the design tool from Texas Instruments to get the values for the components. Here is the circuit: The voltage output seems to be fine. I get 5.1V output. The circuit it's designed to be supposed to handle a...

Hi guys, I'm new year and I'm really stuck. I'm doing research about electromagnetic energy harvesting. I have a wound coil and I'm trying to compensate its inductance using a capacitor. The inductance is around 18 H. The coil resistance fluctuates from 150-190 ohms. I tried adding a 562 nF in a...

Hello I am designing LLC Half-Bridge converter. Pout = 500W Out= 12V Vin=390V Fr = 80kHz Lr = 30 uH, Cr = 120nF , Lp = 190uH The converter is working always above resonant frequency. The oscillographs you see are measured in 200W Pout. As you can see the green channel is Lr current, red channel...

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...

When RLC is in a resonance state that means the total impedance seen by Vs is just Rs. I see no use in this information. This problem kinda confuses me because there's no current flowing into the gate of this transistor so there would be no voltage drop in Rs so the amplitude at the gate would...

Hello ! I've got a question about resonance. I know that the circuit is in resonance when XL = XC. So they are reduced to 0. For example here : If I have here ZL = ZC two times. Like in series resonance, that it is a short-circuit. Does it mean that I reduce every ZL and ZC to zero that the...

Hi all I watched a video that someone used ferrous core and rounded a coil around it and made an oscillator circuit.. and he could make mist with it. I was wondering if we can use suitable size speaker to do the same thing.

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...

Hello all. I am conducting a simulation based report on resonant inductive coupling. I intend to calculate power transferred as a function of input frequency. For this I used the formulae for self resonant frequency and calculated a SRF of 3.283MHz using 10mH, 235pF and 0.25Ohms as my values...

Hello I'm looking for a Magnetic Resonant Wireless Evaluation kit ( with Transmitter and Receiver boards or chips) I can't find it on the Internet and I want to buy it. The distance between the Transmitter to the Receiver has to be at least 5 cm. Best regards, Oriya

When designing a Vacuum tube Teslacoil, must the calculated resonant frequency value of the secondary tank circuit be equal to the calculated resonant frequency value of the primary tank circuit? Im new to this sorry.

I am supposed to calculate the theoretical values for ”natural frequency”, currents and voltages at electrical resonance for this circuit. I should use the measured values for the resistance and the inductance of the coil. Also the measured value of the capacitance to the capacitor. The...
