1. A system controller for regulating a power conversion system, the system controller comprising:
a first transistor including a first transistor terminal, a second transistor terminal, and a third transistor terminal, the first transistor terminal being coupled to a fourth transistor terminal of a second transistor, the second transistor further including a fifth transistor terminal and a sixth transistor terminal;
wherein:
the fifth transistor terminal is coupled to a first resistor terminal of a first resistor, the first resistor further including a second resistor terminal;
the fifth transistor terminal is coupled to a first diode terminal of a first diode, the first diode further including a second diode terminal; and
the second diode terminal is coupled to the second resistor terminal;
wherein the system controller is configured to turn on and off the second transistor.
