Abstract
Controller and method for a power converter. For example, a controller for a power converter includes: a first controller terminal connected to a first base of a first bipolar transistor, the first bipolar transistor further including a first collector and a first emitter; a second controller terminal connected to the first emitter of the first bipolar transistor and a second base of a second bipolar transistor, the second bipolar transistor further including a second collector and a second emitter, the second collector being connected to the first collector; a third controller terminal connected to the second emitter of the second bipolar transistor and a resistor, the resistor being configured to generate a sensing voltage received by the third controller terminal.
