摘要: A method is provided of operating a resonant converter, the converter having controller and power stage providing an output voltage, by determining characteristic frequency stage. The defined as natural oscillation observed right after control signals from are disabled. operated at during ramp-up or ramp-down voltage and/or overload input overvoltage conditions.
