摘要： For starting-up a power converter, an AC rectified voltage is generated upon power-up of the power converter. A depletion mode transistor generates a first voltage from the rectified voltage. The first voltage is inputted to a controller of the power converter to provide power for operation of the controller before an output stage of the power converter starts outputting power. A gate biasing voltage is generated from the first voltage and supplied to a gate terminal of the depletion mode transistor to bias the gate terminal of the depletion mode transistor.
