    The schematic connection of the H-Bridge to the LLC tank is not correct, the return connection must be made to the second pair of switches

    8 күн бұрын

    not only in 6:28 but even in LLC when he put 100Ohm to 500 Ohm, I think should be oposite, as when we push high current to the load we might have a big jump while in low load lower gain jump of gain in resonance. and why ? bicose in heavy load the capacitance impedance when in resonace could be minimum current is high then we have ecessive massive current that is why that the jump
