Switch triggering method for triggering a controlled switch for a switch converter uses a control pulse for switching a direct current input voltage to a transformer's primary winding

摘要

A controlled switch connects an input direct current voltage (UE) with a preset clock pulse frequency (fT) and a preset clock pulse ratio to a transformer's primary winding. The preset clock pulse frequency for a triggering pulse alters via levels (UE1,UE2) of input voltage so that clock pulse frequencies (fT,fT1,fT2) with increasing and falling input voltages are lower and higher. An Independent claim is also included for a switch converter
