Can a Series LC Circuit Effectively Drive MOSFET Gates?

Click For Summary
SUMMARY

The discussion centers on the feasibility of using a series LC circuit to drive MOSFET gates effectively. The proposed circuit utilizes a rectified voltage rail, a resistor for voltage regulation, and a transorb for stability. The user suggests that the 180-degree phase difference between the sine wave in the capacitor and coil allows for sequential switching of MOSFETs, potentially improving efficiency. Additionally, the user seeks a diode that activates at a specific voltage to enhance switching sharpness and reduce heat buildup in the MOSFETs.

PREREQUISITES
  • Understanding of series LC circuits and their behavior in electronic applications.
  • Knowledge of MOSFET operation and gate drive requirements.
  • Familiarity with voltage regulation techniques, including the use of resistors and transorbs.
  • Experience with diode characteristics, particularly in high-frequency applications.
NEXT STEPS
  • Research the design and implementation of series LC circuits for MOSFET gate driving.
  • Learn about the specifications and selection criteria for high-frequency diodes.
  • Explore methods for implementing deadtime in MOSFET switching to minimize heat generation.
  • Investigate the use of transorbs for voltage stability in power electronics applications.
USEFUL FOR

Hi, I have built some stuff before mainly amplifiers and some power supply modules, tell me what you think of this.
I want to ask is it possible to have a series lc circuit that is powered from the rectified + rail through a resistor that gives me the correct voltage and transorb that would make the voltage even more stable then the voltage is fed to the series lc and from the series lc the voltage is extracted to drive the gates of the switch mosfets. Being that the sine wave in the capacitor and the coil is 180 degrees out of phase it should be good as I could switch one mosfet at a time , well ok I'll attach the picture because otherwise my speaking is hard to get I guess.

So what do you think can such a circuit (with additional features ofcourse like safety and voltage control) work?
Share your insight please.

Hi I'm sorry the image attache din the first post isn't the final one this is the better I saw some mistakes in that one, so could you please tell me if the principle I made in this schematic could work well enough.
By the way the place where the sine wave goes to the mosfet gates I would like to use a diode there that would turn on when the sine wave half period reaches certain value , that would give the "fets" some deadtime between switching and also less heat buildup in the devices as the switching would be sharper.

So I'm looking for diodes that let's say starts conduct forward above a certain voltage level and in high frequency.
A thyristor I imagine is one such device but it has gate that needs to be controlled.That complicates the schematic.
