Hello everyone, I'm working on the resonant SEPIC converter topology for an LED driver. My input voltage is 3.7 and the forward voltage of the LED at 1050mA is 2.82-3.15 and the DC forward current is 3 A. Switching frequency is 5MHz.
Here, while the diode is going to cut, L2 and CD resonate...
I know that the ZVS power supply produces a sine wave output due to the oscillation of capacitor and inductor circuit at the output. My question is if I want to take the zero voltage of the sine wave as a terminal where should I connect in the circuit ? Is it the middle tap wire of the coil we...
