Abstract
A switch mode power converter comprises an inverter, a transformer having a primary side winding and a secondary side winding and a first inductor in series with the primary side winding. A second inductor is provided magnetically coupled to the first inductor, and a voltage at one end of the second inductor is used as a feedback signal for indirectly measuring (i.e. approximating) the secondary side voltage, but with measurement at the primary side.
