    摘要: An apparatus, comprising a transformer comprising a first winding and a second winding; a first switch coupled to the first winding and configured to alternate between an off state and an on state in response to a pulsed first signal; a rectifier coupled to the second winding and configured to alternate between an off state and an on state in response to a pulsed second signal; and a drive circuit configured to generate the first and second signals such that the first switch and the rectifier are switched to the on state in a temporally offset relation with each other.

    摘要: An electronic circuit includes a transistor device that can be operated in a reverse operation mode and a control circuit. The transistor device includes a source region, a drain region, a body region and a drift region, a source electrode electrically connected to the source region, a pn junction formed between the body region and the drift region, a gate electrode adjacent the body region and dielectrically insulated from the body region, and a depletion control structure adjacent the drift region. The depletion control structure has a control terminal and is configured to generate a depletion region in the drift region dependent on a drive signal received at the control terminal. The control circuit is coupled to the control terminal of the depletion control structure and configured to drive the depletion control structure to generate the depletion region when the transistor device is operated in the reverse operation mode.
