![]() ![]() Once the circuit really "gets going", I noticed the high side MOSFET experiences a momentary kickback in current during its conduction cycle. Kind of a curious thing when I was playing with my simulation: ![]() I am curious to see if you are able to make this oscillateĮdit: I was doodling around with the Falstad circuit simulator and ended up making oscillations Let me know what you see with the simulations! If I'm wrong feel free to notify me and I will gladly include the reference. I've never seen before a self oscillating RF-resonant half bridge based on two transistors of the same polarity (n-MOS). Note also that the requirements for the capacitive side capacitors (C7, C8) are high - they must endure voltages above 1 kV and reactive powers above 1 kVA.Īs far as I know the circuit is novel. ![]() If You need a moderate voltage but high current, the power can be extracted in the common for all half-bridge circuits way (as shown at the picture - note the load resistor Rload). If You need high voltage - it can be extracted through a capacitive coupling from one or both sides of the main tank coil. The RF power can be extracted in several different ways: Quote The circuit is able to operate at frequencies of several MHZ (tested up to 12 MHz and simulated up to 30 MHz with IRFP460A) and provide several hundreds of watts of RF power (not measured directly - only by simulation and by indirect signs like heating something or lighting a bulb). ![]()
