System and method for regulating a power conversion system. An example system controller for regulating a power conversion system includes a first controller terminal associated with a first controller voltage and coupled to a first transistor terminal of a first transistor, the first transistor further including a second transistor terminal and a third transistor terminal, the second transistor terminal being coupled to a primary winding of a power conversion system, a second controller terminal associated with a second controller voltage and coupled to the third transistor terminal, and a third controller terminal associated with a third controller voltage. The first controller voltage is equal to a sum of the third controller voltage and a first voltage difference. The second controller voltage is equal to a sum of the third controller voltage and a second voltage difference. |

1. A system controller for regulating a power conversion system, the system controller comprising:
a first controller terminal associated with a first controller voltage and coupled to a first transistor terminal of a first transistor, the first transistor further including a second transistor terminal and a third transistor terminal, the second transistor terminal being coupled to a primary winding of a power conversion system; a second controller terminal associated with a second controller voltage and coupled to the third transistor terminal; and a third controller terminal associated with a third controller voltage; wherein:
the first controller voltage is equal to a sum of the third controller voltage and a first voltage difference; andthe second controller voltage is equal to a sum of the third controller voltage and a second voltage difference; wherein the system controller is configured to:
keep the first voltage difference constant; andchange the second voltage difference to turn on or off the first transistor and to affect a primary current flowing through the primary winding. |
