- the switch 6 is closed at a time t2 and opened at a time t3, wherein the distance from t2 to t3 represents a pulse duration.
- This pulse duration is a function of the rectified voltage U-OUT achieved. If the rectified voltage U-OUT achieved is lower than a preset value, the pulse duration is increased. Conversely, the pulse duration is reduced if the rectified voltage U-OUT is higher than the default value.
- control circuit 5 is designed to measure the period and to determine the times t2 and t3 from the default value of the rectified voltage and the actual value of the rectified voltage.
